Question

which of the following are Aps? If they form an
Ap, find the common difference d and write three mere terms .1^2,3^2,5^2,73...​

Answer 1

Answer:

no it is not an a.p

bcoz

= ( 1 ) ^2 = 1

= ( 3 ) ^2 = 9

= ( 5 ) ^ 2 = 25

9 - 1 = 8

25 - 9 = 16

73 - 25 = 48

so their differences are not common
