You hv been given n=2 an Tn=5,n=3 an Tn=7,n=4 an Tn=9,n=7 an Tn=A,n=10 an Tn=21,n=B an Tn=153 determine A and B help please

mathematics sequence and series 
Steve,
so, we have
n Tn
2 5
3 7
4 9
7 A
10 21
B 153
From the first three terms, it looks like
Tn = 2n+1
T10 also fits this, so we have
7 15
76 153
