682 if you include 10 and 672 if you do not include 10.
well, let's break it down. First, the even numbers between 1 and 11 are, 2,4,6,8,10. Now 2+4=6, 6+6=12, 8+12=20, 20+10=30. So, to answer your question simply, the sum of even numbers between 1 and 11, is 30.
The sum of the first 10 even numbers is 110.

sum = 0 for(n = 0; n <= 10; n += 2) sum += n;
The sum of all prime numbers between 10 and 16 is 41.
The composite numbers between 1 and 10 are 4, 6, 8, 9, 10. And their sum is 37.
The sum is 75.
You know that sum of the first n whole numbers is n(n+1)/2. ( it is the same as the first n natural numbers since the zero does not add anything) So lets say you want the sum of all the whole numbers between 3 and 10. ( I made it easy to illustrate the idea.) The sum of the whole numbers between 0 and 3 is 3(4)/2=6 The sum of the whole numbers between 0 and 10 is 10(11)/2=55 So the sum of the whole numbers between 3 and 10 is the (sum of the whole number between 0 and 10) -(sum of whole numbers between 0 and 3) which is 55-6=49 So in general, for whole numbers m and n with m
There is only one even number from 10 to 10, and that is 10 itself.
