may be it is right..............

Answer 2

Natural numbers are always positive and have no decimal values after their main numerical values.

To calculate the 6 divisible number between 17 to 80, we have to manually calculate the first 6 divisible number at first.

And the first number is 18.

Then we just have to add 6 with every number to get the next number with the matching criteria.This will go on untill the number becomes nearest to the last number if this series which is 80.

So,the series will be ;

18;24;30;36;42;48;54;60;66;72;78

[The gap between two numbers is 6]

And there are 11 numbers in this series which is divisible by 6.
