Question

Write down the 1st term in the sequence given by: T(n) = n² - 4

Answer 1

Hi!

To find the first term in the sequence, all you have to do is substitute the n with 1 in the relation, like this:

T(1) = 1² - 4 = 1 - 4 = -3.

Hope this helps!

Answer 2

Explanation:

To generate the first term in the sequence substitute n = 1 into the rule

T(1) = 1² - 4 = 1 - 4 = - 3
