The first 3 terms of a sequence are 2, 7, 22. After the 1st term, each consecutive can be obtained by multiplying the previous term by 3 and then adding 1. What is the sum of the tens digit and the units digit of the 35th term in the sequence?
There is a cycle for every four number: 2,7,22,67; 202,607,1822,5467
Therefore the sum of tens digit and the unit digit of the 35th = 3th
