How do you find the number of even numbers in a set?
Let us consider a set {a,a+1,⋯,b−1,b} where 1
- Case 1 : If a,b are even, the answer is 1+(b−a)/2.
- Case 2 : If a,b are odd, the answer is (b−a)/2.
- Case 3 : If a is even and b is odd, then the answer is 1+(b−a−1)/2.
- Yours is case 4, so the answer is 1+(456−45−1)/2.

How do you find the range of even and odd numbers?
Approach: Total numbers in the range will be (R – L + 1) i.e. N. If N is even then the count of both odd and even numbers will be N/2. If L or R is odd, then the count of odd number will be N/2 + 1 and even numbers = N – countofOdd.
How to count odd or even numbers with formulas in Excel?
Count odd or even numbers with formulas in Excel. 1. In order to count the odd numbers only, enter this formula =SUMPRODUCT((MOD(A1:C8,2)<>0)+0) in a blank cell,, see screenshot: 2. Then press Enter key, and you will get the number of odd values in the selected range.
How do you find the number of odd integers between 1-100?
Look at the top of the range: if it is odd then add 1, if even leave alone. Look at the bottom of the range: if it is odd then subtract 1, if even leave alone. Take the difference between the new even top and bottom; then divide by two. So for the range [ 1, 100] you get 100 − 0 2 = 50 odd integers. Here is another technique i used to follow.
What is the total number of even numbers in the range?
The first even number in the range is: (begin + 1) & ~1 (round begin up to even number). The last even number in the range is: end & ~1 (round end down to even number). The total number of even numbers in the range is therefore: (end & ~1) – ((begin + 1) & ~1) + 1.
