Q: What is the sum of the even numbers from 2 to 250?

Write your answer...

Sum of two odd numbers are always even, and the sum of 2 even numbers are also even. The sum of an odd number & an even number are always odd.

The sum of all even numbers from 2 through 200 is 40,200.

No

The sum of the first 100 even numbers is 10,100

yes,sum of 2 even numbers is always divisible by 2.

The sum of two even numbers is always EVENYes.Proof:We can consider an even number as 2*n, and an odd number as 2*n+1.The sum of two even numbers would be 2*n+2*m=2*(n+m), an even number.

There are 150 even numbers from 2 to 300 with a common difference of 2sum = (a+l)/2*n= 22650

The sum of any pair of prime numbers greater than 2 is an even number.

It is true that the sum of 2 even numbers is never odd

There are 12 even numbers between 2 and 24 inclusive.The sum is 154.

The sum of two even number is always even. So there are no such numbers.

100

The sum of two prime numbers greater than 2 is an even number. The sum of 2 and any other prime number is an odd number.

1,000,000 * * * * * The 1st and 500th sum to (2*1-1)+(2*500-1) = 2*501 - 2 = 1000 The 2nd and 499th sum to (2*2-1)+(2*499-1) = 2*501 - 2 = 1000 There are 250 such sums So sum of all 500 odd numbers = 250*1000 = 250,000

The sum of 2 to 200 = 10,100

Two odd numbers are always even

The sum of the odd numbers (from 1) up to to 500 is 62500. The sum of an arithmetic series is given by: sum = 1/2 x number_in_series x (first + last) For the odd numbers from 1 to 500, there is: number_in_series = 250 first = 1 last = 499 which gives the sum as: sum = 1/2 x 250 x (1 + 499) = 62500.

There is only one even prime number: 2. So, representing 20 as a sum of even prime numbers would be 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2.

Write a recursive function in C to find sum of even numbers from 2 to 50?

The sum of three odd numbers will be odd, whether they are prime or not. The sum of three prime numbers can be even as long as one of them is 2.

It's not possible. For two numbers to have a sum of 13, one would have to be even, that is, divisible by 2.

The numbers are 6 and 8.

The sum of all even numbers between 0 and 398 (2-396) is 157,212. If you include 398 the sum is 158,802.

102

Sum of 1st n even numbers: count*average = n * (2 + 2*n)/2 = n * (n+1) Sum = 50 * (2+100)/2 = 50*51 = 2550
