Question

find the sum of all even numbers between 1 and 350​

Answer 1

Answer:

30102

Step-by-step explanation:

This is an arithmetic progression series where a=2, d=2, tn=350 and we need to find out “n”, using the formula,

Tn = a+(n-1)d

350 = 2 + (n-1)2

348/2 = n-1

n = 173

Substituting the value of n in the formula of Sn, we get

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

Sn = 173/2 [2*2 + (173–1)*2]

Sn = 173/2 * 348

Sn = 30102
