# Write the Arithmetic Progressions Write the First Term a and Common Difference D is as Follows: a = -1.5, D = -0.5 - CBSE Class 10 - Mathematics

#### 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?
