Question

for the AP 3 by 2, 1 by 2, - 1 by 2, -3 by 2 write the first term a and the common difference d ​

Answer 1

Hello,

Here we go,

The AP is given as follows,

3/2,1/2,-1/2,-3/2

So,

First term a = 3/2

Common difference c.d =

1/2-3/2 = -3/2-(-1/2)

1-3/2= -3+1/2

-2/2 = -2/2

-1 = -1

So the common difference is -1.

I hope my answer will help you.
