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:A
Step-by-step explanation:positive is bigger then negative.
Simple ....
we know to find slope is (y1-y2)/(x1-x2)
if we plug in what we know......
(-8,-6),(2,-3)
(-6--3)/(-8-2)
it turns into...
(-6++3)/(-8+-2)
(-3)/(-10)= 3/10
Thus, your answer is that she made no mistake. (C)
Answer: 14 points or 2 touchdowns
Step-by-step explanation:
7 touchdowns times 7 points = 49 points scored by brayden and gavin
9 touchdowns times 7 points - 63 points scored by cole and freddy
63 - 49 = 14
14 points = 2 touchdowns
The answer to this question is 27/28
