Write an explicit formula for a(n), the n^th term of the sequence 180,-30,5

  a(n) = 180·(1/6)^(n-1)

Step-by-step explanation:

The generic formula for a geometric sequence is ...

  a(n) = a(1)·r^(n-1)

Your sequence has a first term of a(1)=180 and a common ratio of r=-1/6, so the explicit formula is ...

  a(n) = 180·(1/6)^(n-1)

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
