Write a recursive formula for the arithmetic sequence:

7,4,1,-2

A1 = 7
a(sub)n = a(sub)n-1 - 3

(sub) indicates the values touching the parenthesis are written as a subscript.

The above would be the recursive formula as you are taking the previous number and subtracting 3 to get the next number in the sequence.

Idon’t know what the answer is i wish i could

The variables should add up to equal 1
