Question

} The nth term of an A.P is given as = + . The common difference is ____.​

Answer 1

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. ... Thus nth term of an AP series is Tn = a + (n - 1) d, where Tn = nth term and a = first term.

Hope it will help you....

Answer 2

Step-by-step explanation:

The common difference of an A.P. is given by an+1−an. ∴d=an+1−an=3+2(n+1)−(3+2n)=2n+2−2n=2. Hence, the common difference d=2.
