Upon adding the even and odd numbers from 1 to 20, you should arrive at the sum of 210.

To make 20 with three different odd numbers, we can use the numbers 1, 7, and 12. 1 + 7 + 12 = 20. These numbers are odd because they cannot be evenly divided by 2. It's important to note that there are multiple combinations of three odd numbers that can add up to 20, such as 3 + 9 + 8 or 5 + 11 + 4.
2 x 2 x 5 = 20 20 is even.
The difference is 2. (23 - 21 = 2).If we are talking about two odd numbers that come right after the number 20 then we mean the two consecutive odd numbers after 20.The difference between any consecutive odd numbers (or between any consecutive even numbers) is always 2.
The first 20 odd numbers are: 13579111315171921232527293133353739.
5 odd numbers CAN'T add up to an even number like 50

If the sum of two numbers is even, the two numbers are either both even or both odd. A few examples:2 + 4 = 6 (even + even = even)2 + 3 = 5 (even + odd = odd)5 + 2 = 7 (odd + even = odd)7+13 = 20 (odd + odd = even)
There are 40 odd numbers between 20 and 100. Remember that an odd number is every second number. There are 80 numbers between 20 and 100, so there are 40 odd numbers and 40 even numbers.
There is no such combination to form an even no. 20 by combing 5 odd nos. as odd+odd=even even +even=evenodd+even=odd even+odd=odd adding 5 odd like
No.. All the numbers end with 0,2,4,6,8 are EVEN NUMBERSso 20 is an even number....

2 x 2 x 5 = 20 20 is even.
There have to be an even number of odd numbers in each group, and each group must have more than two odd numbers (since 19 + 17 is only 36); thus there must be four in one group and six in the other. There are many ways to get four odd numbers to add up to to 50; for example, you could take 1, 13, 17 and 19. The remaining six odd numbers will then also add up to 50.
Any number, regardless of odd or even, if multiplied by an even number, is always even. Ex: 4x6 is 24 4x5 is 20 5x5 is 25
