I had asked readers to find the next number in the sequence 10,9,60,90,70,66
I had also suggested to treat this as an alpha-numeric sequence .
The numbers given are the number of alphabets which are required for expressing the highest numbers with 3,4,5,6,7,and 8 alphabets.
You are thus required to find the highest number which needs 9 alphabets for expression.
No one has given a solution.
Obviously the highest number has to be below 100.
Let us first consider numbers from 90 to 99.
97,98 and 99 require more than 9 alphabets.Only the number 96 requires 9 alphabets and so this is our candidate.
