Mathematics
1 answer:
Maslowich2 years ago

Answer:

<h3>The 7th term is 1458</h3>

Step-by-step explanation:

For a geometric sequence

U(n) = ar^n - 1

Where

n is the number of terms

r is the common ratio

a is the first term

From the sequence

a = 2

r = - 6 /2 = -3

U(n) = 2(-3) ^ n - 1

For the 7th term

U(7) = 2(-3) ^ 7 - 1

= 2(-3)^6

The final answer is

= 1458

Hope this helps you
