I am using `Excel 2016` and I am looking for the formula to determine whether the numbers in a range of cells contain at least 2 consecutive numbers.

Assuming, the range of numbers is between `D1` and `I1` (6 numbers), what would be the formula in cell `J1` to output "Y" (if cells `D1` to `I1` contain a consecutive number), else to output "N"?

This should work:

`=IF(AGGREGATE(14,6,--(E1:H1-D1:G1=1),1)=1,"Y","N")`

How to highlight consecutive or non-consecutive numbers from a , I am looking for a way to determine if a row of 10 cells contain at least 4 number of times there are 4 or more consecutive values in the range  This returns the number of times there are 4 or more consecutive values in the range A2:J2 (B2:E2 has consecutive values and there is only one instance of 4 or more consecutive values); For 10 cells in one column:

```=IF(SUMPRODUCT(--(E1:H1-D1:G1=1),E1:H1),"Y","N")
```

It will fail if the consecutive numbers were -1 and 0. Let me know if this might pose a problem and I should find a cure for it. Here is the formula with the cure implemented.

```=IF(SUMPRODUCT(--(E1:H1-D1:G1=1),COLUMN(E1:H1)),"Y","N")
```

Excel, finding consecutive matching values in a list, Step 1 - Find dates that have a consecutive date except for the last consecutive date. The COUNTIF function Excel basically formats cells containing numbers as dates. You can check this yourself, type 1/1/1900 in a cell. Select the cell and How to calculate overlapping time ranges. I found an old post  To count consecutive duplicates, just need to apply a simple formula. 1. Select an adjacent cell, B1 for instance, enter 1. See screenshot: 2. In the next cell below 1, B2 for instance, enter this formula =IF(A2=A1,B1+1,1), then drag autofill handle down to the cells to apply this formula. See screenshot:

Below formula compares each cell with its adjacent cell plus one. If any of the condition is true it returns "Y" else "N".

`=IF(OR(I1=H1+1,H1=G1+1,G1=F1+1,F1=E1+1,E1=D1+1),"Y","N")`

Find all sequences of consecutive dates, In the example shown, cell I5 contains this formula: COUNTIF counts the number of cells in a range that meet given criteria. If you try to use COUNTIF with​  To count the number of cells that contain values less than a particular number, you can use the COUNTIF function . In the generic form of the formula (above) rng represents a range of cells that contain numbers, and X represents the threshold below

If you couldn't assume that the numbers were pre-sorted, could use:

```=IF(SUM(--(D2:I2=TRANSPOSE(D2:I2)+1)),"Y","N")
```

entered as an array formula using CtrlShiftEnter

This creates a 2D array in which each number in the range is compared against each number in the range +1.

Excel formula: COUNTIF with non-contiguous range, These numbers are supposedly consecutive, but she doesn't know if that is Select the range A2 through the last value in column A. With the  i have to find a formula in excel or code in vba to highlights the 4 consecutive numbers from a cell B2. In this cell are 20 numbers (from 1 to 90). excel vba excel-formula

Identifying Missing Numbers in a Consecutive Series (Microsoft Excel), Locating missing sequential numbers can be an arduous task when working with long For example, you might want to locate business check numbers that haven't enough cells is to select the number of cells equal to the range difference. Re: Check cells for consecutive values Tony's formula, when modified to match the columns used in the file attached to post #5, seems to do what you want. In the attached copy of the file the modified formula is applied to column N of the 2014 and 2013 tabs.

Microsoft Excel: How to Find Missing Numbers in a Sequence , If the destination range includes fewer rows than the argument, the If you want to create consecutive numbers starting at cell A15, enter the formula SEE ALSO COLUMN(), ROWS() SAMPLE FILES Use the ColumnRow worksheet. When you wish to find the number of cells with text in Excel, the COUNTIF function with an asterisk in the criteria argument is the best and easiest solution: COUNTIF( range , "*") Because the asterisk (*) is a wildcard that matches any sequence of characters, the formula counts all cells that contain any text.

At the Select first corner of table cell range: prompt, pick inside the first cell. as consecutive numbers, drag across two cells that already have incremental data. Type the first number into a cell, then type the next number into the cell below it, or to the right of it. Select both of the cells, then click the bottom-right right corner of the selection and drag it down or right until all of the desired cells are selected. You can then let go of the mouse button to fill the cells with consecutive numbers.
