Write first four terms of the AP, when the first term a and the common difference d are given as follows:(i) a = 10, d= 10
(ii) a = –2, d = 0
(iii) a = 4, d = – 3
(iv) a = – 1, d = 1/2
(v) a = – 1.25, d = – 0.25

Explanation

To find the first four terms of an Arithmetic Progression (AP) given the first term \( a \) and the common difference \( d \), we can use the following formulas:

1. First term: \( A_1 = a \)
2. Second term: \( A_2 = a + d \)
3. Third term: \( A_3 = a + 2d \)
4. Fourth term: \( A_4 = a + 3d \)

Now, let's calculate the first four terms for each case provided in the question.
