What is the next number of this series?
1 , 4 , 5 , 6 , 7 , 9 , 11 ?
These are...
numbers not containing the letter "T". The next one is 100.
I know this has already been solved but I have found another solution.
1,4 - 14
41+15=5,6 - 56 reverse of 56 is 65
65+14= 79
97+13=110
11, 0
0 can be the answer!
