Question

Find the sixth term of a geometric sequence with
t5 = 24 and t8 = 3.

Answer 1

t8 = a1 r^7 = 3
t5 = a1 r^4 = 24

t8 / t5 = r^3 = 3/24 = 1/8

so r = ?

Answer 2

r = cube root of 1/8

Answer 3

r=1/2 right

Answer 4

yes

so 6th term = t5 * 1/2

Answer 5

so the 6th term would be 12

Answer 6

yep

Answer 7

awesome. thanks so much for your help :)

Answer 8

common ratio r = 1/2
