number of pairs of odd numbers whose sum is 32: 8
pairs of odd numbers whose sum is 32:
1, 31
3, 29
5, 27
7, 25
9, 23
11, 21
13, 19
15, 17
The sum of an odd number of odd numbers will be odd.
450.
You cannot do this, because you're taking odd numbers: if you add two odd numbers together, you will get an even number. Take the odd numbers in pairs, so you'll have 3 pairs plus an extra odd number. The 3 pairs make 3 even numbers. You can add up any number of even numbers and get an even number, so you will have an even + odd, which is odd. 30 is an even number, but your result will be odd, no matter what 7 odd numbers you choose.
There are no 5 odd numbers whose sum is 50. (The sum of 5 odd numbers is an odd number whereas 50 is an even number.)
There are none. Two odd numbers added together equal a even number.
Yes there is there should be!
The nearest number whose square ≤ 10000 is 100. Then the greatest odd number less that 100 is 99 so there are 50 odd numbers in the range 1- 99 inclusive whose squares are less than 10000.
The factor pairs of 429 (all odd numbers) are (429,1)(143,3)(39,11)(33,13)
There is no set of 3 consecutive odd numbers whose product is 6,873. However, there is a set of 3 consecutive odd numbers whose sum is 6,873: 2289, 2291, and 2293.
1, 3, 5, 7, 9, 11 are six consecutive odd numbers whose sum is 36
There is no set of odd numbers whose product is 56 since the latter is even.
There cannot be any such set of numbers. The sum of any five odd numbers must be odd and so cannot be 70.
