Find an explicit formula for the sequence 30\,,\,150\,,\,750\,,\,3750,...30,150,750,3750,...30, space, comma, space, 150, space,
OverLord2011 [107]
The series shown is an geometric series and the explicit formula is given by:
an=ar^(n-1)
where
a=first term
n=number of terms
r=common ratio
from the sequence:
a=30
r=5
thus the explicit formula will be:
an=30(5)^(n-1)
hence the answer is:
an=30(5)^(n-1)
To find an angle you need to use trig ratios (tan, sin, and cos).
In this case to find ∠R you would need to use sin or cos because both of the legs are not across or adjacent to it.
To find ∠R you would need to do the "opposite" formula which would be (for sin) 5/13 <span>≈ 0.38.. asin = 22.26</span>
