Problem 8- Fibonacci sequence

The Fibonacci sequence is given by,

1, 1, 2, 3, 5, 8, 13, 21, 34, 55,...

Let xi represent the ith term in the sequence. Notice that for i = 3, 4, 5,..., xi is generated by summing the previous two terms. Which of the following generates xi for i = 3, 4, 5,...?

 

 

A.

 

xi = xi-1 +xi-2

B.

 

xi = (i -1) + (i -2) = 2i - 3

C.

 

xi = x1 + x2

D.

 

xi = xi + 1 + xi + 2
E. xi = (i ) + (i -1) = 2i - 1
