Best Answer

Just add the end numbers, so 3 + 5 + 4 + 7 = 19 which is odd.

Alternatively, ignore even numbers [such as 4], and two odd numbers [3 and 5] added always make an even number [8], which leaves and odd number [7] so the answer will be odd. Example; five hundred different numbers, where 483 are even and 17 are odd, then no matter what the actual 500 numbers are the answer will be odd, as there is an odd [17] quantity of odd numbers.

"J" is not a math word, but there are several that beginwith 'j'.Mechanics tend to use the letter "j" instead of the imaginary unit "i", when calculating with complex numbers.

Even plus even equals even. Odd plus odd equals odd. Odd plus even equals odd. 13 + 45 (odd plus odd) will be even. Even plus 24 will be even. Even plus 17will be odd. 13 + 45 + 24 + 17 will be odd.

Actually there are several. If you want the number exactly in between (which won't be an integer in this case), add the two numbers, and divide the result by two.

1,825 days. Just multiply 365 (the number of days in a year) and 5. That's wrong. You have to count with the leap years. When calculating days in a period of several years you have to count one year as 365.25 days. Exactly! So the answer is actually 1825.25

Yes it is possible to determine if a product will be even or odd. To do this, we need to consider what an even number is. Even numbers are numbers with at least one factor of 2 (meaning they are divisible by 2). Thus, any product of numbers which contains at least one even number will result in an even product. If all of the numbers being multiplied together are odd, the product will be odd. If one or more of the numbers is even, the product will be even.
