Question

64,-48,36,-27 which formula can be used to describe the sequence

Answer 1

Answer:

see explanation

Step-by-step explanation:

These are the terms of a geometric sequence with n th term formula

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

r = $\frac{-48}{64}$ = $\frac{36}{-48}$ = - $\frac{3}{4}$

the first term a = 64, hence

$a_{n}$ = 64 $(-3/4)^{n-1}$
