Question

Write the arithmetic progressions write the first term a and common difference d is as follows:

a = -1.5, d = -0.5

Solution

a = -1.5, d = -0.5

Now as a = -1.5

A.P would be represented by `a, a_1,a_2, a_3,a_4.......`

So,

`a_1 = a+ d`

`a_1= -1.5 + (-0.5)`

`a_1 = -2`

Similarly

`a_2 = a_1 + d`

`a_2 = -2 + (-0.5)`

`a_2 = -2.5`

Also

`a_3 = a _2 + d`

`a_3 = -2.5 + (-0.5)`

`a_3 = -3`

Further

`a_4 = a_3 + d`

`a_4 = -3 + (-0.5)`

`a_4 = -3.5`

Therefore A.P with a= 4 and d = -3 is -1.5, -2, -2.5, -3, -3.5.... 

  Is there an error in this question or solution?
