Which number is to the right of the zero (0) and is opposite to -2 on the number line?

Let the unknown number be $x$.
"17 is subtracted from a number" can be written as $x - 17$.
"the result is -10" means the expression equals -10.
So, the equation is:

Add 17 to both sides of the equation:

The number is $\boxed{7}$.

Observe the given numbers: $-5, -4, -3, -2$.
Each number is 1 greater than the previous number. This is an arithmetic sequence with a common difference of $+1$.

Starting from $-2$, add 1 repeatedly:
The next number is $-2 + 1 = -1$.
The second next number is $-1 + 1 = 0$.
The third next number is $0 + 1 = 1$.

The next three numbers are $\boxed{-1, 0, 1}$.
