Answer:
The last term on the paper after 50 students = 
Step-by-step explanation:
The general term of the equation:
Here, the first term = 1
Second term =  2(1) + 1  = 3  = 4 - 1  =  
Third Term = 2(a2) + 1  = 2(3) + 1 = 7  = 8 -1 =   
Fourth term = 2( a3) + 1 = 2(7) + 1 = 15  = 16 - 1  =  
Continuing this way, we get
Last term : 
So, the 50th term of this sequence is

Hence, the last term on the paper after 50th student changes it  =
