Question

Whats the pattern and the next 2 numbers of this question: -1, 2, 7, 17, _, _ .​

Answer 1

see explanation

Explanation:

Consider the differences in the terms

2 - (- 1) = 2 + 1 = 3

7 - 2 = 5

14 - 7 = 7

The differences are 3, 5, 7 ← increasing in steps of 2

Thus the next 2 differences should be 9 and 11

Then the next 2 terms are

14 + 9 = 23

23 + 11 = 34
