The first number in ta sequence is 6. The next number is obtained as follows

(a) Compute the square of the previous number: Example: 6! = 36

(b) Compute the sum of the digits of the result in (a), i.e. 3+6=9

(c) Subtract 2 to the result in (b), that is the next number, i.e. 9 – 2 = 7.

Repeat the procedure on a to c to get the third number sequence. The first three terms in the

sequence is 6, 7 , 11. What is the 2020th number in the sequence?
