If 2 is the first number - what is the next number - 3

If 3 is the first number - what is the next number - 4

How am I getting these next numbers - just adding 1 to the given number - do the same.
 
Is this question looking for a letter number?

If a number n is the first number, what is the second number?
Thank you.

If 2 is the first number - what is the next number - 3

If 3 is the first number - what is the next number - 4

How am I getting these next numbers - just adding 1 to the given number.

so

If 'n' is the first number - what is the next number - just adding 1 to the given number --> (n+1)
