How many even numbers are there between 1 to 100?

I guess this is one you can do almost by listing the even numbers 2, 4, 6, 8, … and counting how many are in the required interval (50). Another, more formalised approach, is to use the formula for the nth term of an arithmetic sequence. t(n)=a+(n-1)d. t(n) is the value of the nth term. a is the first term. read more

Between 1 to 100 there are (100–2)=98 numbers. So, the number of even numbers will be, 98/2=49. But if you include 1 and 100 then, the number of even numbers will be, 100/2 = 50. N.B: Same technique can be applied for finding the number of odd numbers. read more

So there are 50 even numbers from 1 to 100 if you include 100. If you do not include 100 in the count there are obviously 49. The wording of the question is not clear on whether 100 is to be included or not. read more

Every number having 2, 4, 6, 8 and 0 at its one’s place is divisible by 2 and hence, an even number. 3. No number having 3, 5, 7 and 9 at its one's place is divisible by 2 and hence, an odd number. read more
