Question

Check whether given numbers are in A.P: 0.2, 0.22, 0.222, 0.2222, . . . Give the reason to support your answer.​

Answer 1

Step-by-step explanation:

Common difference = difference between two consecutive terms

0.22−0.2=0.02

0.222−0.22=0.002

0.2222−0.222=0.0002

Since the difference between two consecutive terms is not constant

Therefore, the given sequence is not in A.P

Answer 2

Answers:

No

Step-by-step explanation:

a = 0.2

a2 = 0.22

d1 = a2-a

d1 = 0.22-0.2

d1 = 0.02

now, d2 = a3-a2

d2 = 0.222-0.22

d2 = 0.002

as d1 is not equal to d2

imply that it is not an AP
