प्रश्न
Write first four terms of the A.P. when the first term a and the common difference d are given as follows:
`a = -1, d = 1/2`
उत्तर
a = -1, `d = 1/2`
Let the series be a1, a2, a3, a4 …a1 = a = -1
a2 = a1 + d = `-1 + 1/2 = -1/2`
a3 = a2 + d = `-1/2 + 1/2 = 0`
a4 = a3 + d = `0 + 1/2 = 1/2`
Clearly, the series will be `-1, -1/2, 0, 1/2`
First four terms of this A.P. will be `-1, -1/2, 0,1/2 `
