Question

anonymous · Answer

5. State whether each sequence is arithmetic or geometric, and then find the explicit and recursive formulas for each sequence. 
Part 1: 10, 15, 20, 25, 30, ... 

Step 1: State whether this sequence is arithmetic or geometric and find the explicit formula. Show your work. (3 points)  this is a arthimatic because it adds 5 each time 



Step 2: Find the recursive formula. Show your work.  






Part II: 2, 6, 18, 54, 162, ... 
Step 1: State whether this sequence is arithmetic or geometric and find the explicit formula. Show your work. 





Step 2: Find the recursive formula. Show your work.

anonymous · Answer

geometric since you multiply one term by 3 to get the next one

anonymous · Answer

recursive formula says just that 
$$a_1=2,a_n=3a_{n-1}$$
