### Question

Evaluate the following sums:

1 Fib(1)+Fib(2)=____

2 Fib(1)+Fib(2)+Fib(3)=____

### Answer #1 for Questions: Evaluate the following sums:

1 Fib(1)+Fib(2)=____

2 Fib(1)+Fib(2)+Fib(3)=____

## Fibonacci Sequence

One of the most famous formulas in Mathematics. Each number in the sequence is the sum of the two numbers that precede it. Called “nature’s secret code,” and “nature’s universal rule.” It was first discovered or “invented” by Leonardo **Fibonacci**. Italian mathematician, who was born around A.D. 1170, was originally known as Leonardo of Pisa.

### Evaluate the following sums:

1 Fib(1)+Fib(2)=____

2 Fib(1)+Fib(2)+Fib(3)=____

### Answers:

- Fib(1) + Fib(2) =
__Fib(3)__ - Fib(1) + Fib(2) + Fib(3) =
__Fib(4)__

### Solutions and Examples:

1. If Fib(1) = 2 and Fib(2) =3

then,

Fib(1) + Fib(2) = Fib(3)

2 + 3 = Fib(3)

__ 5 = Fib(3)__

2. If Fib(1) = 5, Fib(2) = 6 and Fib(3) = 11

then,

Fib(1) + Fib(2) + Fib(3) = Fib(4)

5 + 5 + 11 = Fib(4)

__ 21 = Fib(4)__
