3 Select the function that defines the given sequence.
–8, -20, -50, –125, 625, ...
OA. f(1) = 8
f(n) = -1(n − 1), for n = 2, 3, 4, ...
OB.
1 () =
= -8•(-9)" – 1)
Oc.
f(n) = -8.()'n – 1)
OD. f(1) = -8
f(n) = . /(n − 1), for n = 2, 3, 4, ...

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
