Question

The expression for the nth term of a sequence is n(n + 7)

What is the 11th term of the sequence?

Answer 1

Explanation:

Write the formula for the nth term of the sequence as a function: f(n)=n(n+7).

So now our goal is to compute f(11). To do that, we substitute x=11 in our function, meaning that the 11th term of the sequence = 11*18, which equals 198.
