# The number which best completes the sequence below is: 2 9 5 13 10 19 17?

**Solution:**

By looking at the sequence one can observe the following pattern:

2 increases to 9 which is an increase of 7.

9 then decreases to 5, a reduction of 4.

5 then increases to 13 which is an increment of 8

13 then decreases to 10 which is reduction of 3

10 then increases to 19 which is an increment of 9

19 then decreases to 17 which is reduction of 2

17 then has to increase by 10 to become 27

**Hence the next number in the sequence is 27.**

## The number which best completes the sequence below is: 2 9 5 13 10 19 17?

**Summary:**

The number which best completes the sequence is 27.
