Question

Find out whether the following sequence form an arithmetic progression and find the common difference: 1) 1/2, 1/4, 1/6, 1/8

Answer 1

Step-by-step explanation:

a1=1/2

a2=1/4

d=a2-a1

1/4-1/2

=. - 1/4

a3=1/6

a4=1/8

d=a4-a3

1/8-1/6

- 1/24

Since their common differences are not same

Hence this sequence don't form ap
