Question

What is the explicit rule for the sequence: 11, 22, 44, 88...

Answer 1

Answer:

Geometric Progression is the explicit rule for the given sequence: 11, 22, 44, 88...

First term (a) = 11

Common ratio (r) = 22/11 = 44/22 = 88/44 = 2

Formula used in Geometric Progression is :---

$\boxed{a_n = a {r}^{(n - 1)}}✓$

where, 'n' is the required term
