What are the explicit equation and domain for geometric sequence with a first term of 4 and a second term of -8

ANSWER

for n≥1

EXPLANATION

The explicit equation for a geometric sequence is found using the formula:

where

is the first term and

is the common ratio.

We substitute the values into the formula to obtain,

This is the explicit formula for the geometric sequence.

The domain is n≥1

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
