Answers for For how many different counting numbers between 10 and 200 is the sum of the digits equal to 6 if zero is not a digit of any numbers?

Between 10 and 100 say we have the number 10a+b where 0<a,b<10.
Now, we want numbers such that a+b = 6. Clearly there are 5 solutions: (a,b) = (1,5),(2,4),(3,3),(4,2),(5,1) corresponding to the numbers 15, 24, 33, 42 and 51.
Now between 100 and 200 we have numbers of the form 100+10a+b with 1+a+b=6 or equivalently a+b=5. Here we have 4 solutions: (a,b) = (1,4),(2,3),(3,2),(4,1) corresponding to the numbers 114, 123, 132 and 141. So all in all we have 9 solutions:
15, 24, 33, 42, 51, 114, 123, 132 and 141

What set of numbers does 45 belong to?
To any set that contains it! It belongs to {45}, or {45, sqrt(2), pi, -3/7}, or all whole numbers between 43 and 53, or multiples of 5, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
What is a consecutive digit?
There's no such thing as one consecutive digit. There has to be at least two of them.When you count, consecutive digits are numbers that you name in a row, with nothing else between them.Examples:34 and 35 are consecutive. There's no counting number between them.97 and 98 are consecutive. There's no counting number between them.62 and 64 are not consecutive, because 63 comes between them.
