Step-by-step explanation:

Answer 2

Answer:

1+2+3+4+5+6+7+8+9+10 will be equal to 55

Step-by-step explanation:

In context to questions asked

We have to determine the value of sum when 1+2+3+4+5+6+7+8+9+10

As here,

We have

Series of natural numbers

Where numbers starts from 1 and ends on 10

So total number of terms will be 10

As we know that

Sum of n natural number can be determined by using formula,

$sum = \frac{n(n + 1)}{2}$

Where n = 10 ( number of terms)

So after putting the value of n we will get the sum as,

$sum = \frac{10 \times (10 + 1)}{2} \\ sum = \frac{10 \times 11}{2} \\ = > sum = 5 \times 11 = 55$
