Write the recursive formula and the explicit formula for the sequence {-15,-7,1,9, 17,...}.
olchik [2.2K]

ANSWER

Explicit formula:

a_n= 8n - 23

Recursive

a_{n}= a_{n - 1} + 8,a_1=-15

EXPLANATION

The first term of the sequence is

a_1=-15

The common difference is

d =  - 7 -  - 15

d = 8

The nth term is given by the formula,

a_n=a_1 + d(n - 1)

a_n= - 15+ 8(n - 1)

a_n= - 15+ 8n -8

The explicit formula is;

a_n= 8n - 23

The recursive definition is

a_{n}= a_{n - 1} + 8,a_1=-15
