Chapter 12: Q. 259 (page 1218)

In the following exercises, write each sum using summation notation.
$4 + 2 + \frac{4}{3} + 1 + \frac{4}{5}$

Short Answer

Expert verified

The summation notation is $\sum_{n = 1}^{5} \frac{4}{n}$ .

Step by step solution

Step 1. Given information.

The given expression is,

$4 + 2 + \frac{4}{3} + 1 + \frac{4}{5}$ .

Step 2. Finding summation notation.

Here, the numerators are all $4$ 's and the denominators are numbers from $1$ to $5$ then we get,

$4 + 2 + \frac{4}{3} + 1 + \frac{4}{5} n : 1, 2, 3, 4, 5 T e r m s : 4, 2, \frac{4}{3}, 1, \frac{4}{5} P a t t e r n : \frac{4}{1}, \frac{4}{2}, \frac{4}{3}, \frac{4}{4}, \frac{4}{5} . . . . . . \frac{4}{n}$

Then the sum can be written in the form of summation notation that is

$4 + 2 + \frac{4}{3} + 1 + \frac{4}{5} = \sum_{n = 1}^{5} \frac{4}{n}$ .
