Math Problem Statement

Write 160 as a sum of nonconsecutive Fibonacci numbers.

Solution

To express 160 as a sum of nonconsecutive Fibonacci numbers, we use the Zeckendorf representation. This representation ensures that each number is represented uniquely as a sum of nonconsecutive Fibonacci numbers. Here are the first few Fibonacci numbers for reference:

F1=1,  F2=1,  F3=2,  F4=3,  F5=5,  F6=8,  F7=13,  F8=21,  F9=34,  F10=55,  F11=89,  F12=144F_1 = 1, \; F_2 = 1, \; F_3 = 2, \; F_4 = 3, \; F_5 = 5, \; F_6 = 8, \; F_7 = 13, \; F_8 = 21, \; F_9 = 34, \; F_{10} = 55, \; F_{11} = 89, \; F_{12} = 144

We will start with the largest Fibonacci number less than or equal to 160, which is 144.

  1. 144: Subtracting this from 160 gives 160144=16160 - 144 = 16.

Next, we find the largest Fibonacci number less than or equal to 16, which is 13.

  1. 13: Subtracting this from 16 gives 1613=316 - 13 = 3.

Finally, we find the largest Fibonacci number less than or equal to 3, which is 3.

  1. 3: Subtracting this from 3 gives 33=03 - 3 = 0.

So, the sum of nonconsecutive Fibonacci numbers that equals 160 is:

160=144+13+3160 = 144 + 13 + 3

Thus, 160 can be written as a sum of nonconsecutive Fibonacci numbers as 160=144+13+3160 = 144 + 13 + 3.
