I don’t know how to solve this question of arithmetic progressions of exercise 5.1 of class 10th. It is very tough for me to solve this question. So how i solve this question 2. Write first four terms of the A.P. when the first term a and the common difference are given as follows:(iv) a = -1 d = 1/2

a = – 1, d = 1/2
Let us consider, the Arithmetic Progression series be a1, a2, a3, a4, a5 …
a2 = a1+d = -1+1/2 = -1/2
a3 = a2+d = -1/2+1/2 = 0
a4 = a3+d = 0+1/2 = 1/2
Thus, the A.P. series will be-1, -1/2, 0, 1/2
And First four terms of this A.P. will be -1, -1/2, 0 and 1/2.
