X =9 had the samw question on sat
THE AWNSER WILL BE 50 YOU TIMES IT BY 2 SO 2 TIMES 25 IS 50 IM IN COLLEGE PEPS I KNOW EVERYTHING
Answer:
True.
Step-by-step explanation:
The explicit form for an arithmetic sequence is:

where
is the first term and
is the common difference.
The common difference here is 2 because the y's are going up by 2 while the x's are going up by 1.
Yes, the common difference is the slope.
So we have d=2.
The first term is 9.5 because that is what happens when x=1.
x is n.
y is
.
So the answer is true.

You can also verify by plugging in numbers for n and see if you get the outputs mentioned in the pairs given:
Let n=1:




Let n=2:




Let n=3:




Let n=4:




Let n=5:




Let n=6:




We have confirmed that we get all 6 of the mentioned points using the equation they gave.
Answer:
the answer would be -4
Step-by-step explanation:
14 - 3(6) = -4
