Write an recursive formula for An, the nth term of the sequence<br> 5, -2, -9,
oksian1 [2.3K]

Given:

The given sequence is:

5,-2,-9,...

To find:

The recursive formula for a_n, the nth term of the sequence.

Solution:

We have,

5,-2,-9,...

Here, the first term is 5.

-2-5=-7

-9-(-2)=-9+2

-9-(-2)=-7

The common difference is -7.

The recursive formula for the nth term of the sequence is

a_n=a_{n-1}+d

Where, d is the common difference.

Putting d=-7 in the above formula, we get

a_n=a_{n-1}+(-7)

a_n=a_{n-1}-7

Therefore, the recursive formula for the nth term of the sequence is a_n=a_{n-1}-7.
