Question

List the first four terms of a geometric sequence with t1 = 4 and tn = -3tn-1.

Answer 1

\(t_1 = 4\)

\[\large t_n = - 3 \cdot t_{n-1}\]

Put n = 2 to find Second term.
Put n = 3 to find Third term.
Put n = 4 to find Fourth term..

Answer 2

is that the complete answer? @waterineyes

Answer 3

That's the complete answer.

Answer 4

whyd you delete it??

Answer 5

Because it was wrong, I'd read your original equation wrong I think. tn=-3tn-1 just says that the term n is -3 times the term before it. So if you have t1 = 4 then t2 will be -3 times 4 = -12. That ok?

Answer 6

thanks!

Answer 7

No problem
