Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.

13. Fibonacci and Lucas numbers
a.) Given four consecutive Fibonacci numbers (this means four Fibonacci numbers in a
row, for example, 1, 1, 2, 3) if you square the middle two and then subtract the
smaller result from the larger result, the result is equal to the
smallest and largest of all four Fibonacci numbers. Fill in the blank and show
several examples that fit this pattern.
of the
Understand the problem:
Given four consecutive Fibonacci numbers → 1, 1, 2, 3
square the middle two –→
1, 12, 22, 3
write the squares
and then subtract the smaller result from the larger result → 4–1 = 3
look at the smallest and largest in the sequence 1, 1, 2, 3 versus the answer of 3.
What can you do to 1 and 3 to get 3? 1
3 = 3
Another example:
Given four consecutive Fibonacci numbers 2, 3, 5, 8
square the middle two → 2, 3², 5², 8

Your own example:
b.) Another sequence that is constructed in a similar way to the Fibonacci sequence is
the Lucas Sequence: 1, 3, 4, 7, 11, 18, 29, 47, 76, 123,
Find the next two numbers in the Lucas sequence.
c.) If you take four consecutive Lucas numbers, square the middle two and then
subtract the smaller result from the larger result, do you get the
smallest and largest, the same way as the Fibonacci sequence? Show several
examples, then state your conclusion.
