B. X,2X,3X cuz the sum of X and 2X is 3X
This is an arithmetic sequence because each term is 1/8 more than the previous term. This is called the common difference and it is what defines an arithmetic sequence.
a(n)=a+d(n-1), where a is 1st term, d is common difference, and n it term #
In this case:
a(n)=3.25+0.125(n-1) or more neatly...
a(n)=3.125+0.125n
a(5)=3.75
the answer is B. $16.00 because when you do the math it comes up to 15.98
The answer is 1. Please mark brainelist
