Find the explicit formula for a 1 =-4,a n =a n-1 +9,n>=2
Mrrafil [7]

Given:

a_1=-4 and a_n=a_{n-1}+9 where n\geq 2.

To find:

The explicit formula for the given recursive formula.

Solution:

We know that recursive formula of an AP is:

a_n=a_{n-1}+d

Where, d is the common difference.

We have,

a_n=a_{n-1}+9

Here, d=9.

The first term of the AP is a_1=-4.

The explicit formula for an AP is:

a_n=a_1+(n-1)d

Substituting a_1=-4 and d=9, we get

a_n=-4+(n-1)9

a_n=-4+9n-9

a_n=-13+9n

Therefore, the required explicit formula for the given sequence is a_n=-13+9n.
