24 (as with the other examples) is not written 'twentyfour' though, it's 'twenty-four'. 17 is the only 9-letter single-word number.

I was wondering if 'googolplex' would be a valid 10-letter single-word number. The only problem is, writing it out as a number is going to be tricky :-)

23 is definitely the next number but, followed by 18

halftimeorange; do you have an explanation as to why those are the next 2 numbers?

Thanks for the update. Is that the official answer, as I can see the 23 but as for the 18 can;t see how it work's?

[halftimeorange]

I will answer the question in due course.

Bobbinwales or Elliemay1 what is your reasoning for it being 23
