Question

Identify which of the following sequence is an A.P.i)1/2,2/3,3/4,4/5,5/6,....​

Answer 1

Step-by-step explanation:

A1 = 1/2

A2 = 2/3

A3 = 3/4

we know, for the series to be in ap , d= A2 - A1 = A3 - A2

therefore, d= 2/3 - 1/2

= (4 - 3)/6 = 1/6

d = 3/4 - 2/3

=(9 - 8)/12 = 1/12

therefore, the series is not in ap
