Inspired by another question here, I thought I might create my own:
Fill in the correct number in this sequence:
5, 3, 4, 9, 8, 3, 5, ...
And of course, explain why :)
I believe the answer is
My reasoning is
Taking each word of the sentence "Fill in the correct number in this sequence:", count the number of letters and add the number of vowels. Equivalently, each consonant adds 1, and each vowel adds 2 to the sum of the word.
The numbers given correspond to "Fill... this" so the next word is "sequence". With eight letters, four of which are vowels, the total would be 12.
