A1=16 and a3=4 what is the common ratio
what is the explicit rule? (example: a1(r)^n-1, obviously you will be replacing the a1 and r for the number)

Step-by-step explanation:

A geometric sequence is generated by multiplying the first term in the sequence, , several times by a fixed scalar . and so on, down to ..Using the result above, the sequences you're interested in are

31)  

33)

We can rewrite these results to make them slightly cleaner.

answer: a.   one is a factor of every whole number since every number is divisible by itself.

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
