$1$ $\underline{\text{Fibonacci Sequence}}$  \vspace{2mm}  According to some accounts, Fibonacci is regarded as one of the most famous names in mathematics. It was Fibonacci, also known by the name Leonardo Pisano, that helped popularize our modern number system in the Latin-speaking world (Knott, 2013). However, he is more widely recognized for what we now call the Fibonacci Sequence. It was when he was contemplating the reproduction of rabbits, and trying to calculate how many pairs of rabbits there would be in one year, that Fibonacci came across the formula, which will become familiar: $x_{n+1}=x_n+x_{n-1}$. \vspace{2mm}  This recurrence relation was used to define the Fibonacci Sequence as such: $F_n=F_{n-1}+F_{n-2}$ where $F_1=F_2=1$. Calculating the first few terms we see the numbers $1,1,2,3,5,8,13,21...$. These numbers are called the Fibonacci numbers.
