Answer: 110.6
Step-by-step explanation: 220 - 109.4 = 110.6
Since it is a geometric sequence each term will be a specific multiple of the term preceding it, called the common ratio...
126/42=378/126=1134/378=3
The sequence is a(n)=a(3)^(n-1) and we know the second term is 42 so:
42=a(3)^(2-1)
42=3a
a=14
So the first term is 14.
Answer:A= 7
Step-by-step explanation:
y=mx+b
512=114x+134
subtract 134 from both sides of the equation,
378=114x
Divide 144 from both sides of the equation to get x by itself
x=6.25
you'll round up because you can't really have a quarter day.
A= 7
