Question 2 of 44beginner🔧 ApplyShort Answer4 marks
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
Answer
10, 20, 30, 40
(ii)
a = -2, d = 0
Answer
-2, -2, -2, -2
(iii)
a = 4, d = -3
Answer
4, 1, -2, -5
(iv)
a = -1, d = 1/2
Answer
-1, -1/2, 0, 1/2
Explanation
To find the first four terms of an AP, we use the fact that each succeeding term is obtained by adding the common difference d to the preceding term. The first term is a, second term is a + d, third term is a + 2d, and fourth term is a + 3d.
