Question

find the sum of the finite series.
\sum_{n=1}^{10} 3

Explanation:

Step1: Understand the summation

The summation $\sum_{n = 1}^{10} 3$ means we are adding the constant 3 ten times (since $n$ ranges from 1 to 10).

Step2: Calculate the sum

The formula for the sum of a constant $c$ from $n = 1$ to $n = k$ is $S=k\times c$. Here, $k = 10$ and $c = 3$. So we calculate $10\times3$.
$10\times3 = 30$

Answer:

30
