Write the arithmetic progressions write the first term a and common difference d is as follows:
`a = -1, d = 1/2`
उत्तर
`a = -1, d = 1/2`
Now as a = -1
A.P would be represented by `a,a_1, a_2,a_3,a_4......`
So,
`a_1 = a + d`
`a_1 = -1 + (1/2)`
`a_1 = (-2 + 1)/2`
`a_1 = (-1)/2`
Similarly
`a_2 = a_1 + d`
`a_2= (-1)/2 + (1/2)`
`a_2 = 0`
Also
`a_3 = a_2 + d`
`a_3 = 0 + (1/2)`
`a_3 = 1/2`
Further
`a_4 = a_3 +d`
`a_4 = (1/2) + (1/2)`
`a_4 = 2/2`
`a_4 = 1`
Therefore, A.P with a = 4 and d = -3 is `-1, (-1)/2 , 0 , 1/2, 1,.... `
