Question

If the nth term of a number sequence is n2-5, find the first 3 terms and the 10th term

Answer 1

9514 1404 393

Answer:

• -4, -1, 4
• 95

Explanation:

Use n = {1, 2, 3, 10}.

n^2 -5 = {1, 2, 3, 10}^2 -5 = {1, 4, 9, 100} -5 = {-4, -1, 4, 95}

The first three terms are -4, -1, 4.

The 10th term is 95.
