Depends what you mean by 'sequence'; 2,4,6,8 is a sequence, so is 5, 10, 15,
20 and then there is 1, 1, 2, 3, 5, 8....but I cannot spell Fibonacci!

If you mean a sequence where each value is the previous value plus 1:
With your numbers in A1:A8
In B2 enter =IF(A2=A1+1,"",A1+1&" missing")
Copy down the column

is it possible find missing numbers in a sequence?

example:
1
2
3
5
6
7
9
10

4 and 8 are missing.
