Question

These are the first six terms of a sequence starting with a1=18.

18,37,56,75,94,113,…
Find a recursive and an explicit formula for this sequence.
The recursive formula should depend on an–1.
Recursive formula: an=
Explicit formula: an=

Answer 1

Recursive formula: an= a(n-1) + 19

Explicit Formula : an= 19n-1

I hope this helps :)
