Question

The nth term of a sequence is 2n²-4. What is the 10th term of the sequence?

Answer 1

196

Explanation:

To find the 10 th term, substitute n = 10 into the rule, that is

`a_(10)` = 2(10)² - 4 = 2(100) - 4 = 200 - 4 = 196

Answer 2

To find the value of the 10th term substitute n with 10 in the rule.

= 2(10)^2 - 4

= 2(100) - 4

= 200 - 4

= 196 (10th term in the sequence)

Best of Luck!
