It is: 2*3*5*7 = 210
The sum of the first 30 positive even numbers is 930.
5 (2 + 3), 7 (2 + 5), 8 (3 + 5), 9 (2 + 7) and 10 (3 + 7).
Either a negative or a positive result depending on the values of the numbers as for example -7+9 = 2 but -9+7 = -2
the answer is 49.

The first ten positive numbers total 55.
Assuming the two numbers are positive integers, the two numbers must be 10 and 7: 10 + 7 = 17 10 - 7 = 3
negative
1+3+5+7+9=25
The sum of the first 1,000,000 positive even numbers is: 2 + 4 + 6 + 8 + ... + 2,000,000 The sum of the first 1,000,000 positive odd integers is: 1 + 3 + 5 + 7 + ... + 1,999,999 The difference between the two is: (2-1) + (4-3) + (6-5) + (8-7) + ... + (2,000,000-1,999,999). This is the same as: 1 + 1 + 1 + 1 + ... + 1. Well how many 1's are there? 1,000,000. So the difference is 1,000,000. Note that if the question asked for the difference between the sum of the first 1,000 positive even numbers and the sum of the first 1,000 positive odd numbers, the answer would be 1,000. The first n even numbers and odd numbers? n.
There aren't two positive consecutive numbers that have an LCM of 200.There aren't two positive consecutive numbers that are multiples of 7.Other than that...
The first 10 positive odd numbers are 1, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
