Q. 6 B5.0( 4 Votes )

Show that each of the following sequences is an A.P. Also, find the common difference and write 3 more terms in each case.

Answer :

A.P is known for Arithmetic Progression whose common difference = an – an-1 where n > 0

As, a2 – a1 = a3 – a2 = a4 – a3

The given sequence is A.P

Common difference, d

To find next three more terms of A.P, firstly find an

We know, an = a + (n-1) d where a is first term or a1 and d is common difference

When n = 5:

a5 = 4

When n = 6:

When n = 7:
