Question

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

Answer 1

a1 = -6

a2 = 30

a3 = -150

a4 = 750

a5 = 3750

Step-by-step 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`
