The number 0.3333... repeats forever, therefore, it is irrational.
A. True
B. False

B. False

Step-by-step explanation:

If the decimal goes on and on forever and never stops or begins to repeat predictably, it's irrational. If the decimal stops after a finite number of digits or begins to repeat predictably, it's rational.

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,
