Question

Find the 6th term of the sequence in which t1 = -5 and tn = -5tn-1.

Answer 1

You have \[t _{n}=-5t _{n-1}\] correct?

Answer 2

yea

Answer 3

ok, so each succeeding value is just -5 times the previous value.

Answer 4

so \[t _{6}=t _{0}\left( -5 \right)^{6-1}\] and t_0=1

Answer 5

so that would be -25

Answer 6

ummm...t_2=25, but t_6 is way more than that.

Answer 7

(-5)x(-5)x(-5)x(-5)x(-5)=-3125

Answer 8

ok thank you!!! :)

Answer 9

YW!
