~Determine whether each sequence is arithmetic or geometric fund the next three terms~
*Doing a math unit test and stuck on these five*
1.14,19,24,29....

2.-2,8,-16,32...

3.81,27,9,3...

4.What are the first four terms of an arithmetric sequence if the common diffrence is 1.5 and the first term is 15

5.What are the first four terms of a geometric sequence if the common ratio is 10 an the first term is 4.5

1. Steve

if the difference is constant, it's arithmetic. If the ratio is constant, it's geometric.

#1 is clearly arithmetic
#2 is geometric
#3 is too

#4 15 + 1.5 + 1.5 ...
#5 4.5 * 10 * 10 ...
