Question

Show that the progression 8, 11, 14, 17, 20, ... is an AP. Find its first
term and the common difference.​

Answer 1

Answer:

d =a2-a1

=3

If all term satisfies here and common difference is 3 it is an ap.

So,this is an AP

First term=8

Answer 2

$\small\bold{\underline{\sf{\blue{solution:-}}}}$

d =a2-a1

=3

If all term satisfies here and common difference is 3 it is an ap.

So,this is an AP

First term=8
