    n represents the amount of chandeliers you have. b(n)=6n represents how many lightbulbs are needed with respect to the amount of chandeliers you have

    \[b(n)=6n\] \[b(15)=6(15)\] \[b(15)= 90\]

    Okay! Thank you, so much! And I have another question, if you wouldntr mind helping?? Bamboo plants grow rapidly. A bamboo plant is 130 inches tall. Tomorrow it will be 143 inches tall, the next day it will be 156 inches tall, and on the next day it will be 169 inches tall. Write a rule to represent the height of the bamboo plant as an arithmetic sequence. How tall will the plant be in 13 days?

    No, not for this problem. I mean you need to find the formula that sequences this problem.
