a) Use 2 as your starting exponent

3 is the base of all exponents

6 is the maximum exponent

 



b)  Recognize a Growth Pattern
 
 because 

, as described in the sigma notation

: 22-2+1=21. 

Starting at the second term and going up to the 22nd term

Add the 1 due to inclusion of the 2nd term
 
 is a Finite Geometric Series

Use sum of a geometric series formula
