You could say that a(n) = 12 - 5n .
Then ...
a(1) = 12 - 5 = 7
a(2) = 12 - 10 = 2
a(3) = 12 - 15 = -3
and so on.
So it seems to work.
Answer:
37.25, 35.5, 33.75, <u>32</u>, <u>30.25</u>.
Step-by-step explanation:
Subtract the first term from the second term:
35.5 - 37.25 = -1.75
Subtract the second term from the third term:
35.5 - 33.75 = -1.75
The common difference is -1.75.
To find each subsequent term, add the common difference to the current term.
33.75 + (-1.75) = 32
32 + (-1.75) = 30.25
Answer:
37.25, 35.5, 33.75, <u>32</u>, <u>30.25</u>.
Answer:
Yes it is talking about more than one person
It'd be best if you'd stick to symbols. My interpretation of what you've typed here is 20x - 20x^2 + 5x^3. In descending order by powers of x, that gives us
5x^3 - 20x^2 + 20x.
