Let's relax and play a math game The first part: take a natural number N1 = 5, calculate N1 & # 178; + 1 to get A1; Part two: calculate the sum of all the numbers of A1 to get N2, calculate N2 & # 178; + 1 to get A2; Part 3: calculate the sum of the numbers of A2 to get N3, and then calculate N3 & # 178; + 1 to get A3; …… By analogy, a2013 = ▁▁▁▁▁▁▁▁▁▁

Count the first three
a1=26 n1=5
a2=65 n2=8
a3=122 n3=11
n4=5
Find the rules?!
a2012=122
a2013=26
