The Total solution for NCERT class 6-12
The Fibonacci sequence is defined by
1 = a1┬а= a2┬аand an┬а= anтАУ 1┬а+ an тАУ 2, n > 2
Find an+1/an, for n = 1, 2, 3, 4, 5┬а
Given,
1 = a1┬а=a2
an┬а= anтАУ 1┬а+ an тАУ 2, n > 2
So,
a3┬а= a2┬а+a1┬а= 1 + 1 = 2
a4┬а= a3┬а+a2┬а= 2 + 1 = 3
a5┬а= a4┬а+a3┬а= 3 + 2 = 5
a6┬а= a5┬а+a4┬а= 5 + 3 = 8
Thus,
