Sum of Even Numbers
The first 161 even numbers range from 2 to 322. On this page, we will show you how to calculate the first 161 positive even whole numbers by using our formula.
The formula to calculate the sum of even numbers is: sum = n × ( n + 1) where n is the even numbers. When we enter 161 into our formula, we get the following:
161 × (161 + 1)
= 26082
Therefore, the sum of the first 161 even numbers is 26082
Answer:
6080
Step-by-step explanation:
Given : a= 2
d= 2
An = 160
An= a +(n-1)d ( putting value )
160 = 2+ (n-1) 2
160 = 2n
n= 80
Sn=n/2 × (2a+ (n-1)d) ( putting value of n)
=> 80/2 × (4 + 2n-2)
=> 40 × 2 + 2n
=>38 × 2(80)
