Answer 2

110

To Find:  

The sum of the first 10 even natural numbers that are there.

The formula that is used for calculating the sum of n term of an AP:  

Sn = n/2(2a + (n - 1) d

The first term of the AP = 2

The value of n = 10

The common difference of the AP(d) = 2

Substituting all the values which are known to us into this formula we get:  

Sn = 10/2 (2 x 2) + (10 - 1) x 2

Sn = 5 (4 + 9 x 2)

Sn = 5 x (4 + 18)

Sn = 5 x (22)

Sn = 110

Therefore, the sum of the first 10 even natural numbers is 110.
