Question:

What Are The first three terms of the sequence described by the nth term n2-3




Answer:


a_n = n² - 3

a_n = a with a subscript of n (this is the nth term in the sequence)

n = number of terms


This is a Square Number Sequence.


the first three terms in the sequence are:


if n = 1, the first term is

a_1 = 1² - 3

a_1 = 1 - 3

a_1 = -2



if n = 2, the second term is

a_2 = 2² - 3

a_2 = 4 - 3

a_2 = 1


if n = 3, the third term is

a_3 = 3² - 3

a_3 = 9 - 3

a_3 = 6
