Sorry. No sum of even numbers can be an odd number.
No, the sum of three odd numbers will always be odd.

There are never 3 even numbers that add up to an odd number because all of the numbers are even so the result/sum will have to be an even number.
24 and 21?

No, the sum of three odd numbers will always be odd.
The sum of two evens is even so the sum of any number of evens is even. It is, therefore, impossible for the sum of three even numbers, whether or not consecutive, to be 57, which is an odd number.
The numbers are -30, -28 and -26.
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.
The prime numbers between 40 and 60 are 41, 43, 47, 53 and 59. These sum to 243.
False. The sum of 3 and 3 is 6. And 6 is even. The product of two odd numbers is always odd. false the sum of 2 odd numbers is always even 3+3=6 5+5=10 103+103=206
If the question is asking for the sum of natural numbers between two members of N, then you will have to add all the natural numbers between the two numbers (excluding the actual two numbers). For example, if they ask you to calculate the sum between 2 and 5, your answer should be 3+4=7.

If the average of 3 numbers is 37 then the sum of those numbers = 37 * 3 = 111. Which is an odd number. Adding together even numbers never results in an odd number. Therefore the 3 numbers can not be even numbers; consecutive or otherwise. The question can not be answered.
