## Find the longest/smallest consecutive sequence of a value

The array formula in cell D3 returns the the length of longest consecutive sequence of a value in column A. Cell D4 returns the value of the longest consecutive sequence in column A.

Cell F3 returns the the length of the shortest consecutive sequence of a value in column A and cell F4 returns the value of the smallest consecutive sequence in column A.

**How to enter an array formula**

- Select cell
- Copy/Paste the formula to the formula bar
- Press and hold CTRL + SHIFT simultaneously

I wish I could present a smaller formula.

### Length of shortest consecutive sequence of a value

### Functions in this post

**FREQUENCY(***data_array*, *bins_array***)
**Calculates how often values occur within a range of values and then returns a vertical array of numbers having one more element than the bins_array

**IF(**logical_test;[value_if:true];[value_if_false]**)
**Checks whether a condition is met, and returns one value if TRUE, and another value if FALSE.

**SMALL(**array,k**)**

Returns the k-th smallest number in this data set.

**ROW(**reference**)
**Returns the rownumber of a reference.

**MATCH(**lookup_value, lookup_array, [match_type**]

This reminded me of a article I wrote a while back, only I took the perspective of using this methodology to calculate win/loss streaks for a sports team. There's a lot of cool stuff you can do with this consecutive sequence formula!

Chris Macro,

Yes, there is a lot of cool stuff you can do I only wish I could come up with shorter formulas.

The FREQUENCY function really saved me, I thought quite a while before figuring out how to solve this problem.

Thanks for sharing your post.

I got an email from David, his formulas are a lot smaller.

Formula in D4:

=INDEX($A$2:$A$25,AGGREGATE(14, 6, ROW($A$3:$A$26)-2/(FREQUENCY(IF($A$2:$A$25=$A$3:$A$26, ROW($A$2:$A$25)), ($A$2:$A$25<>$A$3:$A$26)*ROW($A$2:$A$25))=(D3-1)), 1), 0)

I have this sequence of C2: O2,

2 1 2 X X X 2 X 1 X 2 X 2

I need you to return the largest consecutive sequence:

X should be 3

2 should be 2

1 should be 1

x and 2 should be 4.

Another example:

X 2 X 1 1 X 1 1 X 1 1 1 2

1 X must be

2 must be 1

1 must be 5

x and 2 should be 2.

Tenho esta sequencia de C2:O2,

2 X X X 1 2 2 X 1 2 X X 2

Preciso que retorne a maior sequencia consecutiva de:

X deve ser 3

2 deve ser 2

1 deve ser 1

x e 2 deve ser 4 .

Outro exemplo:

X 2 1 X 1 X 1 1 1 1 1 2 X

X deve ser 1

2 deve ser 1

1 deve ser 5

x e 2 deve ser 2 .
