Answer:A=250, B=1250, C=6250

Step-by-step explanation:

2,10,50,A,B,C

common ratio=50/10=5

A=50x5=250

B=250x5=1250

C=1250x5=6250

Might have to experiment a bit to choose the right answer.

In A, the first term is 456 and the common difference is 10.  Each time we have a new term, the next one is the same except that 10 is added.

Suppose n were 1000.  Then we'd have 456 + (1000)(10) = 10456

In B, the first term is 5 and the common ratio is 3.  From 5 we get 15 by mult. 5 by 3.  Similarly, from 135 we get 405 by mult. 135 by 3.  This is a geom. series with first term 5 and common ratio 3.   a_n = a_0*(3)^(n-1).
So if n were to reach 1000, the 1000th term would be 5*3^999, which is a very large number, certainly more than the 10456 you'd reach in A, above.

Can you now examine C and D in the same manner, and then choose the greatest final value?  Safe to continue using n = 1000.

Find the average rate of change for f(x) = x2 + 9x + 18 from x = −10 to x = 10.
igor_vitrenko [27]
The average rate of change formula is 
           f(b) - f(a)
arc = ----------------
               b-a
                    
Here, a= -10 and b = 10

                   (10)^2 + 9(10) + 18 - [ (-10)^2 + 9(-10) + 18]
Here arc = --------------------------------------------------------------
                                     10 - (-10)

10^2 and -(-10)^2 cancel.     18 - 18 cancel.

                                               90 - (-90)            180
This leaves us with     arc = ----------------- = ------------- = 9 (answer)
                                                   20                     20
