Question

Write the recursive formula for the sequence represented by the explicit formula and the first term. a n =0.4(8)^ n-1

An= (An-1)
A1=

Answer 1

Answer:

A recursive sequence is a sequence in which terms are defined using one or more previous terms which are given. If you know the nth term of an arithmetic sequence and you know the common difference , d , you can find the (n+1)th term using the recursive formula an+1=an+d
