Question

Find the next three term in the sequence-8, 24,-72,216

Answer 1

- 648, 1944, - 5832

Explanation:

the terms form a geometric sequence with

common ratio r =
`(-72)/(24)` =
`(24)/(-8)` = - 3

to obtain the next term in the sequence multiply the previous term by r

216 × - 3 = - 648

- 648 × - 3 = 1944

1944 × - 3 = - 5832

the next 3 terms are - 648, 1944, - 5832
