Write the first three terms of the AP's, when a and d are as given below
(i) `a=(1)/(2), d= -(1)/(6) " " ` (ii) `a= -5, d= -3`
(iii) `a=sqrt(2), d=(1)/(sqrt(2))`

Explanation

To find the first three terms of the arithmetic progression (AP) for each case, we will use the formula for the terms of an AP:

1. The first term (T1) is \( a \).
2. The second term (T2) is \( a + d \).
3. The third term (T3) is \( a + 2d \).

Let's solve each part step by step.
