The third term of an arithmetic progression is 25 and the tenth term is -3. Find the first term and the common difference?

Expert Solution

Sol.

We have to find the first term a, and the common difference, d from the given information (i.e. third term T₃= 25 and T₁₀ = -3).

To determine first term a, and the common difference, d from the given information we proceed as follows:

So, from the above calculations:

the first term a, = 33 and

the common difference, d = - 4

The first term a, = 33 and the common difference, d = - 4
