Question

How do I solve these problems ? I'm suppose to write the first five terms of each sequence

Answer 1

ANSWER

a1 = -6

a2 = 30

a3 = -150

a4 = 750

a5 = 3750

EXPLANATION

The first 5 terms are a1, a2, a3, a4 and a5. To find them we just have to replace n by the number of term 2, 3, 4, or 5. For the first term we don't have to do this because it's already given:

$a_2=-5a_1=-5\cdot(-6)=30$$a_3=-5a_2=-5\cdot30=-150$$a_4=-5a_3=-5\cdot(-150)=750$$a_5=-5a_4=-5\cdot750=3750$
