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