Question

8. nth term of on to an A.P is an=3+2n.
Find the common difference
​

Answer 1

Given, nth term of an AP is an = 3 + 2n.

The first term :

• a1 = 3 + 2(1) = 3 + 2 = 5

The second term :

• a2 = 3 + 2(2) = 3 + 4 = 7

Common difference, d = a2 - a1

ﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠ= 7 - 5

ﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠ= 2

Answer:

The common difference, d is 2.
