1, which is 2 b/c all of the other even numbers are divisible by 2, therefore making it composite.
2 is the only one.
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
all numbers between 1-100 that can be divided exactly by 2.examples: 2,4,6,8,10,12,14,16,18, 20...100!
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.
