Answer:
GIVEN
We are given an Arithmetic Progression whose firstbterm is -7 and common difference is 4
TO FIND
We need to find the 25th term of the AP
FORMULA
The nth term of an AP can be calculated by the formula
A(n) = A + ( n-1 )× d
SOLUTION
A = -7
d = 4
A(25) = -7 + (25-1) × 4
A(25) = -7 + 96
A(25) = 89
The 25th term of the AP is 89
