The fibonacci sequence looks like the following:
1, 1, 2, 3, 5, 8, 13, 21, ...
What are the next 3 terms in the sequence?
What is the rule?
34, 55, 89
a given number in the sequence = the sum of the previous two numbers
Are the points B, C, and E collinear, coplanar, both or neither?
Coplanar- not collinear
Points A, B and C are collinear and Point B is between A and C. AB=2x-3, BC=3, and AC=x+6. Find AC.

BC=65
A famous math problem, the Monty Hall Problem:
Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the doors, opens another door, say No. 3, which has a goat. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?
Switch!
This is wild, but you have a 2/3 chance of winning if you switch and a 1/3 chance of winning if you stick with your choice.

BINARY NUMBERS: Computers think differently than you and I. They can only understand numbers in terms of 0 and 1, so they use something called binary numbers. Here are the first 10 numbers in binary.
1 = 1; 2 = 10; 3 = 11; 4 = 100; 5 = 101; 6 = 110; 7 = 111; 8 = 1000; 9 = 1001; 10 = 1010
What is 11 in binary? (BONUS: 12, 13, 14?)
What is the pattern?
11 = 1011; 12 = 1100; 13 = 1101; 14 = 1110
Pattern: Each digit represents 2 to that power. Any number can be written by writing 0 or 1 in each digit in order to add to the total.
The first digit = 2^0 = 1
Second digit = 2^1 = 2
Third digit = 2^2 = 4
Fourth digit = 2^3 = 8
