Question

Write the first four terms of the AP when 1^( st ) term a=-1 and common difference d=1/2

​

Answer 1

a=1 and d=1/2

so.

First four terms are 1, 3/2, 4/2, 5/2

Answer 2

Answer: The series be−1,(−1/2),0 and  1/2

Step-by-step explanation:

Arithmetic progression is represented by a,(a+d),(a+2d),(a+3d), .

where a is the the first term, d is the common difference

So, here the First term f=-1

Second term=-1+(1/2)

Third term=-1+2(1/2)

Fourth term=-1+3(1/2)

Therefore, the series be −1,(−1/2),0 and  1/2
