प्रश्न
Write first four terms of the A.P. when the first term a and the common differenced are given as follows:
a = 4, d = -3
उत्तर
a = 4, d = -3
Let the series be a1, a2, a3, a4 …
a1 = a = 4
a2 = a1 + d = 4 - 3 = 1
a3 = a2 + d = 1 - 3 = -2
a4 = a3 + d = -2 - 3 = -5
Therefore, the series will be 4, 1, -2 -5…
First four terms of this A.P. will be 4, 1, -2 and -5.
