Answer 2

Answer:

The sum of n terms of an arithmetic sequence can be calculated by S

n

=

2

n

[2a+(n−1)d]

Where n = number of terms ⇒ 20

a = first even term ⇒ 2

d = common difference of A.P. ⇒ 2

Apply the given data in the formula,

S

20

=

2

20

[2×2+(20−1)2]

=10[4+38]

=10[42]

=420

So, the sum of first 20 even terms of the A.P. is 420.
