Known sequence 1,5,9 The general formula of 101 is an; arithmetic sequence 3,5,9,15 The general term formula of 105 is BN to find the same term of {an} and {BN}

BN suspected that it was wrong. How could 105 appear? It was totally out of line with the law
If 105 is changed to 135, it can be calculated
The calculation is as follows:
an=4n-3
bn=n(n-1)+3
Order:
ax=4x-3(x
