Question
Write the arithmetic progressions write the first term a and common difference d is as follows:
a = 4,d = -3
Solution
In the given problem, we are given its first term (a) and common difference (d).
We need to find the A.P
a = 4,d = -3
Now as a = 4
A.P would be represented by `a, a_1,a_2,a_3,a_4 ..........`
So,
`a_1 = a + d`
`a_1 = 4 + (-3)`
`a_1 = 1`
Similarly
`a_2 = a_1 + d`
`a_2 = 1 + (-3)`
`a_2= -2`
Also
`a_3 = a_2 + d`
`a_3 = -2 + (-3)`
`a_3 = -5`
Futher
`a_4 = a_3 + d`
`a_4 = -5 + (-3)`
`a_4 = -8`
Therefore, A.P with a= 4 and d = -3 is 4, 1, -2, -5 , -8......
