Question

The common difference of AP 3/2,7/2,11/2,15/2​

Answer 1

Answer:

Here,

a=3/2 and b=7/2

Therefore ,

Common difference,d=b-a

=7/2-3/2

=4/2

=2

So the common difference is 2

Hope it helps you

Answer 2

Given:

A.P.: 3/2, 7/2, 11/2, 15/2​

To find:

The common difference

Solution:

The common difference is 2.

We can find the difference by following the given steps-

We know that the given series is an arithmetic progression.

So, each term of the given series increases by the same number.

This number is called the common difference of the A.P.

The common difference can be obtained by subtracting any two consecutive terms of the series.

Let the common difference be D.

Now, D can be obtained by subtracting any two consecutive terms.

The first term of the A.P.=3/2

The second term of the A.P.=7/2

The common difference=Second term-first term

D=7/2-3/2

D=4/2

D=2

This can be calculated by subtracting any two other consecutive terms too.

Therefore, the common difference is 2.
