Question

Select the option fo “?” That continues the pattern in each question.
3, -6, 12, 4, 20, ?

Answer 1

The sixth number in series is 13.

Explanation:

Given series : 3, -6, 12, 4, 20, ?

The pattern followed by the series is:

The first number = 3

Second number = 3 - 9 = - 6

Third number = - 6 + (9 ×2) = -6 + 18 = 12

Fourth number = 12 - 8 = 4

Fifth number = 4 + (8 ×2) = 20

Sixth number = 20 - 7 = 13

Seventh number = 13 + (7 ×2) = 13 + 14 = 27 and so on.

So as per the above pattern, the sixth number in the series is 13.
