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

Find the sum of first 10 even numbers?
The sum of the first 10 even numbers is 110.
What happens to the median when you come up with two answer?
when you have an even amount of numbers while trying to find the median, you first find the two numbers that are at the median and then take all the numbers between them and find the median of that. if that amount of digits is also even, then you must have a decimal median.
The product of 2 consecutive even numbers is 840. Find the numbers?
The product of two consecutive even integers is 840.find these numbers
If the sum of two consecutive even integers is -298 What are the integers?
-150, -148 To find these numbers set up an algebraic expression. The first even integer would be 2X and the next even integer would be 2X + 2 So, 2X + (2X+2) = -298 Solving for X, X = -75 So the first even integer would be 2*(-75) or -150 And the second even integer would be 2 + the first or 2+-150 or -148
How do find the median if there are an even number of entries?
If you have to find a median in a set of numbers in which there are an even number of entries, you must find the average of the two numbers the come in the middle.
How you would find the sum of the first fifty even numbers?
Add them together.
Find the sum of first 10 even numbers?
The sum of the first 10 even numbers is 110.
What happens if the number you are trying to find the medium for is even?
You find the median for the two middle numbers. For example; your numbers are 5 6 7 8. First, you follow the steps. Cross out the side numbers so you are left with 6 and 7. Then you find the middle of those two numbers, which in this case would be 6.5
Find the total of the first three even numbers?
The sum of the first three even positive integers is 2 + 4 + 6 = 12.
What is the formula to find out the sum of first n even numbers?

Find the sum of the first 50 even numbers what is the sum?
of all the things i got is 2550
What is the median for first 20 prime numbers?
The median for the first 20 prime numbers would be 30. This is because the middle two numbers of the first 20 prime numbers are 29 and 31. To find the median from this, we need to find the average of these two numbers. This is 30.

How do you find the median of an even set of number?
Find the average. That is, add all of the even numbers together, then divide that by the number of even numbers.
If the sum of two consecutive even integers is -298 What are the integers?
-150, -148 To find these numbers set up an algebraic expression. The first even integer would be 2X and the next even integer would be 2X + 2 So, 2X + (2X+2) = -298 Solving for X, X = -75 So the first even integer would be 2*(-75) or -150 And the second even integer would be 2 + the first or 2+-150 or -148
Find the difference between the sum of the first 1000000 positive even numbers and the sum of the first 1000000 positive odd numbers?
The sum of the first 1,000,000 positive even numbers is: 2 + 4 + 6 + 8 + ... + 2,000,000 The sum of the first 1,000,000 positive odd integers is: 1 + 3 + 5 + 7 + ... + 1,999,999 The difference between the two is: (2-1) + (4-3) + (6-5) + (8-7) + ... + (2,000,000-1,999,999). This is the same as: 1 + 1 + 1 + 1 + ... + 1. Well how many 1's are there? 1,000,000. So the difference is 1,000,000. Note that if the question asked for the difference between the sum of the first 1,000 positive even numbers and the sum of the first 1,000 positive odd numbers, the answer would be 1,000. The first n even numbers and odd numbers? n.
