Write a formula
The above sequence shows a geometric sequence because:
-- common ratio
The equation is determined using:
Where
Substitute values for a and r
Apply law of indices:
<em>The above represents the explicit formula</em>
Answer:
Step-by-step explanation:
1) divide each term in the numerator by the term in denominator:
(remember when dividing subtract the smaller exponent from larger exponent
for example: say a is the larger exponent, do
x^4/x=x^3
5x^3/x=5x^2
3x^2/x=3x
so
x^3+5x^2+3x
