Question

Find the first six terms of the sequence.

a1 = -6, an = 4 • an-1

Answer 1

The first term is a1 = -6. This is given

The next term must be found using the rule an = 4 • a(n-1)

Answer 2

This rule says "multiply the previous term by 4 to get the next term"

So a2 = 4*a1 ----> a2 = 4*(-6) = -24

Answer 3

What is a3?

Answer 4

\(\Large \bf a_1=-6\qquad a_{\color{red}{ n}}=4\cdot a_{{\color{red}{ n}}-1}\\ \quad \\

a_{\color{red}{ 2}}=4\cdot a_{{\color{red}{ 2}}-1}\qquad a_{\color{red}{ 3}}=4\cdot a_{{\color{red}{ 3}}-1}\qquad ...\)
