Question

Find the first six terms of the sequence.

a1 = -8, an = 5 • an-1

-8, -40, -200, -1000, -5000, -25,000
-8, -40, -35, -30, -25, -20
0, 5, -40, -35, -30, -25
-40, -200, -1000, -5000, -25,000, -125,000

Answer 1

-8 is the first term
...and your second term can be found by multiplying 5 to your previous term

Answer 2

\[a_n=5 \cdot a_{n-1} \text{ this says \to find next term just multiply previous term by 5}\]

Answer 3

so the second term would be -40? because 5 x -8 = -40?

Answer 4

\[\text{ replace } n \text{ with 2} \\ a_2=5 \cdot a_{2-1} \\ a_2=5 \cdot a_1 \]
see you are just multiplying previous term by 5 to find the term

Answer 5

yep

Answer 6

ok thank you!

Answer 7
