Chapter 12: Q 69. (page 809)

In Problems 61–70, express each sum using summation notation.
$a + (a + d) + (a + 2 d) + . . . . . . . . + (a + n d)$

Short Answer

Expert verified

The required summation notation is $a + (a + d) + (a + 2 d) + . . . . . . . . + (a + n d) = \sum_{k = 0}^{n} (a + k d)$

Step by step solution

Step 1. Write the given information.

The given sum is:

a + (a + d) + (a + 2 d) + . . . . . . . . + (a + n d)

Step 2. Write the sum using summation notation.

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

Therefore, $a + (a + d) + (a + 2 d) + . . . . . . . . + (a + n d) = \sum_{k = 0}^{n} (a + k d)$ .
