Question

What would be the next number in the series 9, 8, 18, 6, 36, 4, 72, 2, 144, ?

Answer 1

$\textbf{\large{Answer -}}$

9, 8, 18, 6, 36, 4, 72, 2, 144, $\textbf{\underline{0}}$

Explanation :

Starting from the series, every alternate number is the product of 2 and the number. For example,

$9 × 2 = 18$

$18 × 2 = 36$

$36 × 2 = 72$

$72 × 2 = 144$

Then, the from every number two is subtracted. For example,

$8 - 2 = 6$

$6 - 2 = 4$

$4 - 2 = 2$

$\textbf{2 - 2 = 0}$

Answer 2

Answer is 0.

9 x 2 = 18
18 x 2 = 36
36 x 2 = 72
72 x 2 = 144

8 - 2 = 6
6 - 2 = 4
4 - 2 = 2
2 - 2 = 0 (Ans)
