Question

An arithmetic sequence is represented by the recursive formula A(n) = A(n-1) + 8. If the first term in the sequence is 4, write the explicit formula

Answer 1

Answer:

A(n) = 4 + 8(n-1)

Step-by-step explanation:

A(n) = A(n-1) + 8

A(1) = 4

So A(2) = A(1) + 8 = 4 + 8

A(3) = A(2) + 8 = A(1) + 8 + 8 = 4 + 8 + 8

A(n) = 4 + 8(n-1)
