Question

2. Find the sum of 100 terms of an A.P : 2, 4, 6, ………., 200 ?

Answer 1

Answer:

10100

Step-by-step explanation:

Sum of 100 terms of AP = Sn = n/2 (a + l)

a = first term = 2

l = last term = 200

Sn = 100/2 ( 2 + 200)

= 50 × 202

= 10100

sum of 100 terms of AP is 10100

hope you get your answer.
