Question

2, 11, 7, 16, 12, ?, 17, 26

Answer 1

21

Explanation:

The pattern for this sequence of numbers is +9, -4

2 + 9 = 11

11 - 4 = 7

7 + 9 = 16

16 - 4 = 12

12 + 9 = 21

21 - 4 = 17

17 + 9 = 26

Therefore, the missing number in this sequence is 21.

Answer 2

8

Explanation:

The pattern in the sequence is that the difference between adjacent terms alternates between 9 and -4. So to find the missing number, we need to subtract 4 from 12, which gives us the answer of 8. Therefore, the missing number in the sequence is 8.
