Answer 2

Answer:

i hope this answer is right

Step-by-step explanation:

Zero.

Consider the lesser case, the sum of all one digit numbers divisible by 7.

There are two, 7 and -7. Adding 7 to -7 we get zero.

There’s no need to go through the process of finding all the two digit numbers that are divisible by 7, because it is immediately obvious that each will have a negative and a positive counterpart, and that each will thus sum to zero.

2 times 7 is 14, -2 times 7 is -14, so on and so forth.

The sum of the positive such numbers is 728, but the sum of negative such numbers is -728, so the sum of all such numbers is 0.
