Question

For given A.P. $-\frac{1}{2},-\frac{3}{2},\frac{1}{2},-\frac{3}{2},..$ find the common difference.

• A. $-1$
• B. $-\frac{1}{2}$
• C. $\frac{3}{2}$
• D. $1$

Answer 1

The correct option is A $-1$

The general form of A.P. is $a,a+d,a+2d,a+3d.....$
$-\frac{1}{2},-\frac{3}{2},\frac{1}{2},-\frac{3}{2},..$
Here the common difference is $-1$.
