Answer:

90

Explanation:

To solve this we will use concepts of arithmetic progression from class 10.

The first term is = a = 0

The total terms are = n = 10

The difference between each term of the arithmetic progression is = d = 2 (because the difference between simultaneous even numbers is 2)

Sum of the terms of the arithmetic progression = S

Now applying the formula.

S = n/2 [a+(n-1)d]

S = 10/2 [0+(10-1)2]

S = 5[18]

S = 90

So the sum of the first 10 even numbers is 90.
