Determine whether the progression above is arithmetic, geometric, harmonic, or none of the above. If arithmetic or harmonic, state the common difference, d. If geometric, state the common ratio, r.    

An additive sequence is one where the next term is found by [answer1] and an arithmetic sequence is one where the next term is found by [answer2].

Insert a geometric mean between 6 and 24. 

Consider this problem: If 8 pints of ice cream costs a baker $52, how much will 15 pints cost? Choose one of the following methods to solve the problem: (a) The Rule of Three or (b) Proportions Be sure to show ALL work! Again, you only need to solve using one of the methods! Round this answer to two decimal places.

 Insert a geometric mean between 3 and 12. 

Consider this problem: If 15 pints of ice cream costs a baker $75, how much will 18 pints cost?
