Question

For the ap 3/2. 1/2. -1/2.-3/2... write the first term a and common difference d ​

Answer 1

First term is
`(3)/(2)`.

Common difference: -1

Explanation:

Given the sequence:

`(3)/(2) , (1)/(2) , -(1)/(2), -(3)/(2), ...`

we notice that one term is generated from the previous one by subtracting from it "1". That means that the common difference for this sequence is "-1", and its first term is
`(3)/(2)`.
