Question

64,-48,36,-17... which formula can be used to describe the sequence?

Answer 1

Answer:

Explicit formula is an = 64(-3/4)^(n-1).

Step-by-step explanation:

Looks like a geometric sequence with a negative common ratio.

-48/64 = - 3/4

36 / -48 = -3/4

Now -27/36 = -3/4 so I think there's a typo in the question. Its -27 not -17.

The required formula is 64(-3/4)^(n-1) .
