Subject: "Have your program add one to the number" ?

I'm starting to learn Ruby using the Learn to Program book by Chris
Pine.

On a mini assignment I need to:

"Write a program which asks for a person's favorite number. Have your
program add one to the number, then suggest the result as a bigger and
better favorite number. (Do be tactful about it, though.) "

Here's what I have so far...

1 full_name = first_name + ' ' + middle_name + ' ' + last_name
2 puts full_name + ', ' + 'What\'s your favorite number???'
3 favorite_number = gets.chomp
4 new_number = favorite_number.to_i + 1
5 puts 'hmmm... What about ' + new_number + '? ' + 'It\'s bigger and
better than yours :)'

The program runs smoothly until line 4 than it returns the following
error:

:in `+': can't convert Fixnum into String (TypeError)

Could you please point my mistake?

Thanks,
Fellipe
