Question

The common difference of A.P. 5, 9, 13, 17 is .....

Answer 1

Given,

A given A.P.: 5, 9, 13, 17

To find,

The common difference of the given A.P.

Solution,

We can simply solve this mathematical problem using the following process:

Mathematically,

The common difference of an A.P. is equal to the difference between any two consecutive terms, that is, the difference between a term of the A.P. with its just previous term of the A.P.

Now,

The common difference of the given A.P.

= (Second term of the A.P.) - (First term of the A.P.)

= 9-5 = 4

Hence, the common difference of the given A.P. is equal to 4.

Answer 2

Answer:

4

Step-by-step explanation:

5,9,13,17,...

t1=5 ,t2=9 ,t3=13 ,t4= 17.

d= t2-t1 = 9-5 =4

d= t3-t2 = 13-9 =4

d= t4-t3 = 17-13 =4

d=4
