Question

What are the first four terms of the sequence modeled by the recursive formula a n =a n-1 +5, when a1 = -3?

Answer 1

Answer:2,7,12,19

Step-by-step explanation:

a2=a2-1+5=-3+5=2

a3=a3-1+5=a2+5=2+5=7

a4=a3+5=12 and continue so on

Answer 2

The first four terms are
a1= -3
a2= -18/5
a3= -21/5
a4= -24/5
