Chapter 12: Q 69. (page 809)

In Problems 61鈥�70, express each sum using summation notation.

a+a+d+a+2d+........+a+nd

Short Answer

Expert verified

The required summation notation is a+a+d+a+2d+........+a+nd=鈭�k=0na+kd

Step by step solution

01

Step 1. Write the given information.

The given sum is:

a+a+d+a+2d+........+a+nd
02

Step 2. Write the sum using summation notation.

As we can see that the sum a+a+d+a+2d+........+a+ndhas n+1terms, starts at k=0and ends at k=n.

Therefore, a+a+d+a+2d+........+a+nd=鈭�k=0na+kd.
