Question

Which formula can be used to describe the sequence? -2/3 , −4, −24, −144,...

Answer 1

Answer:

Concept:

A sequence is said to be in geometric progression if each term is obtained by multiplying a constant number to the immediately preceeding term.

Given sequence:

-2/3, -4, -24, -144................

Here, each term of the sequence is obtained by mutiplying 6 to the immediately preceeding term.

Hence, the given sequence is in G.P.

Also, the n th term of the sequence can be written as

$t_n=\frac{-2}{3}(6)^{n-1}$
