The sum of first 10 even whole numbers is

1. 110

2. 90

3. 55

4. 45

The first 10 even whole numbers are 0, 2, 4, 6, 8, 10, 12, 14, 16 , 18.

Sum of an A.P. is given by,

$S$n = \dfrac{n}{2}(a + l) \\[1em] \therefore S{10} = \dfrac{10}{2}(0 + 18) \\[1em] = 5 \times 18 \\[1em] = 90.

Hence, Option 2 is the correct option.
