Just count up all the even numbers which will all be divisible by 2
Numbers up to 200 divisible by both 2 and 3 = numbers to 200 divisible by 2*3 = 6 which is int(200/6) = int(33.33) = 33
There are 45 prime numbers that are less than 200 (including '1'.)

Look up Gauss' Formula if you want to know how to calculate this. If you just want the answer, it's 20100.
0,1,3,6,10,15,21,28,36,45,56,68,81,95,110,126,143,161,180,200. That's all the triangular numbers up to 200! I hope that's helped anyone with any thing.

Numbers up to 200 divisible by both 2 and 3 = numbers to 200 divisible by 2*3 = 6 which is int(200/6) = int(33.33) = 33
There are exactly 200 of them.
There are 45 prime numbers that are less than 200 (including '1'.)
add up all the numbers, then divide by the amount of numbers. (in this case divide by 7
There are 80 such numbers.
