Write the recursive formula for the geometric sequence. a1 = -2 a2 = 8 a3 = -32

Recursive formula for the geometric sequence is,

Step-by-step explanation:

A geometric sequence states that a sequence in which the ratio of any term to the previous term is constant.

A recursive formula states that it uses the preceding term to define the next term of the sequence.

For the geometric sequence, the recursive formula is given by;

where r is the common ratio.

Given the following:

, and

The common ratio for the geometric sequence , r =-4

Since,

..

Then, the recursive formula for the geometric sequence is,

or
