Look for a pattern and then predict the general term, or nth term, an, of the sequence.-1, 4, -16, 64, -256, . . .
A. an = (-1)n4n B. an = (-1)n4n-1 C. an = (-1)n4n D. an = (-1)n-14n-1
A population changes with time. Its level after t years is given by the function 
. After a period of population decrease, the population reaches a minimum value. What can be said about 
at this time?
?
A. is positive.
B. is negative.
C. is zero.
D. is linear.
Use inductive reasoning to predict the next line in the pattern. Then perform the arithmetic to determine whether your conjecture is correct.8 × 9 = 10 × 11 - (8 + 9 + 10 + 11)9 × 10 = 11 × 12 - (9 + 10 + 11 + 12)
A. 10 × 11 = 12 × 13 - (10 + 11 + 12 + 13) B. 10 × 11 = 12 × 13 - (8 + 9 + 10 + 11 + 12 + 13) C. 11 × 12 = 13 × 14 - (10 + 9 + 8 + 7) D. 11 × 12 = 13 × 14 - (11 + 12 + 13 + 14)
