Question

Find a formula for the nth term of the sequence whose first few terms are shown.
-1/64, -1/4, -4, -64, -1024

Answer 1

\[\LARGE n ^{th} term = {-1\over64} * [16 * (n-1)] \]

Answer 2

I can explain it to you along with a few examples if you need.

Answer 3

can you explain it for me

Answer 4

\[
a_n =-\frac 1 {64} 16^{n-1}
\]

Answer 5

Okay, so like the 2nd term is given, substituting all the variables, we get:
\[\LARGE 2^{nd} term= {-1 \over 64} * [16 * (2-1)] = {-1 \over 64} * 16 = {-1\over 4} \]
