For the following sequences calculate the indicated term:
a) , 

All you do is substitute 5 for n and simplify







b) , 

ln(en) simplifies to just n, so the
problem is only

, 

Just substitute 13 for n and have 

 





c) , ,  

This is a recursive formula, not a general formula,
like the other two.  

1. You are given a1.
2. You use n=1, a1 and the formula to find a2.
3. You use n=2, a2 and the formula to find a3.
4. You use n=3, a3 and the formula to find a4.

1. 

2. Substitute 1 for n and 1 for a1, and
simplify:

 





3. Substitute 2 for n and 3 for a2, and
simplify:


 




4. Substitute 3 for n and 7 for a3, and 
simplify:
