Questions: Enter the value of ∑ from n=3 to 5 of (n+2)

Transcript text: Enter the value of $\sum_{n=3}^{5} n+2$

Solution

To solve the given summation, we need to evaluate the expression $ n+2 $ for each integer $ n $ from 3 to 5 and then sum the results.

Step 1: Define the Summation Range

The summation is defined for $ n $ ranging from 3 to 5. We need to evaluate the expression $ n+2 $ for each integer value of $ n $ within this range.

Step 2: Evaluate the Expression for Each $ n $

Calculate $ n+2 $ for each $ n $:

Step 3: Sum the Results

Add the results from the previous step: \[ 5 + 6 + 7 = 18 \]

\[ \boxed{18} \]
