1 + 3 + 5 + 71
there are many combinations
17, 19, 21 and 23.
84
23+21+19+17=80
Oh, what a lovely puzzle to solve! Let's paint a happy little picture here. If we have four odd numbers that are multiples of 5 and their sum is 80, we can see that the numbers are 5, 15, 25, and 35. Each number is odd, a multiple of 5, and when you add them together, you get a beautiful total of 80. Happy painting!
It is 23 because 17+19+21+23 = 80
four consecutive odd, whole numbers cannot have an average of 549. four odd numbers added together would be an even number. an even number divided by another even number (in this case, four) will only yield an even number.
There are 39 odd numbers between 1 and 80.
50
80
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.
82
There are two consecutive odd, whole numbers. The numbers are 39 and 41.
