Given,
A.P -10,-8,-6,..,88
To Find,
last fifth term of the A.P
Solution,
In the given A.P
a=-8
d=2
a+(n-1)d=88
-8+(n-1)2=88
2n-2=96
2n=98
n=49
So, the fifth last term will be 45
a₄₅= a+44d
= -8+44(2)
= -8+88
= 80
Therefor, the fifth last term is 80.

We must recall that:
Arithmetic progression is a progression in which every term after the first is obtained by adding a constant value, called the common difference (d). So, to find the nth term of an arithmetic progression, we know
Given:
A.P
In the given A.P
So, the fifth last term will be 45
Therefore, the fifth last term is 80.
