Question

If nth term of an a.p is an =n2-1 then its 3rd term will be

Answer 1

helo guys its your answer

Step-by-step explanation:

On putting n = 1, 2, 3, 4, 5 then can get the first five terms ... The given sequence whose, an = n2 - n + 1 ... Write the arithmetic progression when first term a and common difference d are

Answer 2

Answer: The third term of the AP is 8.

The nth term of an arithmetic progression (AP) can be represented by the formula:

                       $a_n = a_1 + (n-1)d$

where a1 is the first term of the AP, d is a common difference, and n is the term number.

In this case, we are given that the nth term of the AP is given by an = n² - 1.

To find the third term of the AP, we need to substitute n = 3 into the given formula for an:

                         $a_3 = 3^2 - 1\\ a_3 = 9 - 1\\ a_3 = 8$

Therefore, the third term of the AP is 8.
