Breaks most of my rules, but included to help people taking IQ tests.

The next term is 34-in-base-12 which is "2 10", and so cannot be shown here.

Fibonacci numbers expressed in base 12 end in the following two-digit combinations: {00, 01, 01, 02, 03, 05, 08, 11, 19, 2a, 47, 75}. Every twelfth term is divisible by 12^2. Note: here the digit "a" = decimal 10. - Michael De Vlieger, Nov 11 2014
