SOLUTION :

GIVEN

• The sum of 5th and 8th term of an AP is 37

• The 11th term is 32

TO DETERMINE

The Arithmetic progression

FORMULA TO BE IMPLEMENTED

If in an arithmetic progression

First term = a and common difference = d

Then n th term of the AP is

EVALUATION

Let in the arithmetic progression

arithmetic progression First term = a and common difference = d

So

5th term = a + ( 5 - 1 ) d = a + 4d

8th term = a + ( 8 - 1 ) d = a + 7d

11th term = a + ( 11 - 1 ) d = a + 10d

So by the given condition

Also

Now 2 × Equation (2 ) - Equation (1 ) gives

From Equation (2)

So

First term = a = 2

Second Term = a + d = 2 + 3 = 5

Third Term = a + 2d = 8

Fourth term = a + 3d = 11

...........

Hence the arithmetic progression is

2 , 5 , 8, 11 , .....
