Question

Next number in pattern
7,11,12,18,-7?

Answer 1

7,8,10,14,22,?

Let the unknown be X.

Observing the pattern, we get

8–7 = 1

10–8 = 2

14 - 10 = 4

22 -14 = 8

X - 22 = 16

( Because the difference, is the Geometric Sequence, with common ratio = 2).

Therefore,

X = 22 + 16 = 38

The next term in the given sequence is 38.
