Common difference = 2nd term - first term
= -13-(-6)
= -13+6
= -7

Given:
The sequence is -8, -12, -16.
To find:
The nth and 52th term of the given sequence.
Solution:
We have,
-8, -12, -16
It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is




The nth term of an AP is

Where, a is first term and d is common difference.
Putting a=-8 and d=-4, we get



Putting n=52, we get



Therefore, the equation for the nth term of the given sequence is
and the 52nd term of the sequence is -212.
