Step-by-step explanation:
GIVEN
We Are given an Arithmetic Progression which the first term is 3 , and the common difference is (8-3) , d= 5
TO FIND
We need to find the 30th term of this arithmetic progression.
FORMULA
To find the nth term of an AP , we use the formula :-
T(n) = A + (n-1)d
where A is the first term , n is the number of terms and d is the common difference
SOLUTION
A = 3
d = 5
n = 30
T(30) = 3 + ( 30-1)×5
==> T(30) = 3 + 145
==> T(30) = 148
The 30th term of the AP is 148
