Given that:
a1=27, an=(an-1)+4
the second term will be:
a2=a1+4
a2=27+4=31
The explicit formula for arithmetic sequence is given by:
an=a+(n-1)d
where:
a= first term
d=common difference
n=nth term
from the information given:
a=27
d=31-27=4
thus the explicit formula will be:
an=27+(n-1)4
an=27+4n-4
an=23+4n
Answer: an=23+4n
Answer:
See below
Step-by-step explanation:
This is a reflection in the x axis ( the 2 ---> -2) and a translation up of 3 units (The +3).
It is helpful to become familiar with the rules for secants of a circle.
