Question

What is the recursive rule for the sequence:

11, 22, 44, 88...

Answer 1

The recursive rule for the sequence is

`a_n= 2a_(n-1)` ,

where n is positive integer.

Explanation:

Given sequence is

11,22,44,88........

Here the first term of the sequence is = 11

Second term of the sequence is = 22

Third term of the sequence is = 44

Fourth term of the sequence is = 88.

............

Second term = 2×first term

Third term = 2 × Second term

Fourth term = 2 × Fourth term

The recursive rule for the sequence is

`a_n= 2a_(n-1)` ,

where n is positive integer.
