NEED HELP

Answer 1

The answer is - 65

Explanation:

From the question the nth term of the sequence is

3n² - 10

where n is the number of terms

Since we are finding the 5th term

n = 5

Substitute this value into the above formula

That's

3(5)² - 10

= 3( 25) - 10

= 75 - 10

We have the final answer as

- 65

Hope this helps you
