Question

For the Ap : 3/2 , 1/2 , - 3/2 ,...., write the first term a and the common difference d (answer in step by step)​

Answer 1

Step-by-step explanation:

first term = 3/2

common difference d = A2 -A1

= 1/2 -3/2

= -2/2

= -1

Also for verification d = A3 - A2

= -3/2 - 1/2

= -2/2

= -1

so a = 3/2 and d = -1
