Question

if forms an AP find common difference d and write 3 more terms -1/2,-1/2,-1/2.....​

Answer 1

Given A.P. : -1/2, -1/2, -1/2 .....

So, a = -1/2

d = -1/2-(-1/2) = 1/2 + 1/2 = 0

Thus, we conclude that it is a constant A.P. i.e., every term of the AP is equal.

Hence, 3 more terms : -1/2, -1/2, -1/2

Answer 2

Answer:

A.P=-1/2,-1/2,-1/2……

a=-1/2

d=0

n=4

an=a+(n-1)d

a4=-1/2+3(0)

a4=-1/2

n=5

a5=-1/2+(4)0

a5=-1/2

n=6

a6=-1/2+(5)0

a6=-1/2
