Find the third term of the geometric sequence when a^1=1/4 and r=−2

Step-by-step explanation:

Since the sequence is a geometric sequence

For an nth term in a geometric sequence

where n is the number of terms

a is the first term

r is the common ratio

From the question

a = 1/4

r = - 2

Since we are finding the third term

n = 3

So the third term of the sequence is

We have the final answer as

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
