Question

A sequence is defined by the function f ( n ) = f ( n − 1 ) + 5 , where n represents the number of the term for n > 1 , and f ( 1 ) = − 4 . What are the first four terms of the sequence?

Answer 1

Explanation:

if f(1)=-4, then adding 5 would give you 1, again would give you 6, again would give 11. Therefore, your first four terms are -4,1,6,11.
