Question

check whether 5a,7a,9a....is an AP if it form an AP find common difference​

Answer 1

Answer:

yes it is in AP

Step-by-step explanation:

By finding the common difference

A2 - A1 = 7a-5a = 2a

A3 - A2 = 7a - 9a = 2a

so, A3-A2= 2a =A2-A1.

the common difference is 2a

Answer 2

Answer:

yes, It is an AP . Because common difference is

same.

step -by-step explain

A1=5a

A2=7a

A3=9a

by finding common difference

d = A3-A2

d = 9a-7a

d = 2a

d = A2-A1

d = 7a-5a

d = 2a

so, this is prove that 5a,7a,9a,.... is an AP
