Math Problem Statement
write 160 as the sum of a nonconsecutive Fibonacci numbers
Solution
The Fibonacci sequence starts as: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, and so on. To express 160 as a sum of non-consecutive Fibonacci numbers, we can use Zeckendorf's Theorem, which states that every positive integer can be uniquely represented as a sum of non-consecutive Fibonacci numbers.
Let's break down 160 using the Fibonacci sequence:
-
The largest Fibonacci number less than or equal to 160 is 144.
-
Subtracting 144 from 160 gives:
-
The largest Fibonacci number less than or equal to 16 is 13.
-
Subtracting 13 from 16 gives:
-
The largest Fibonacci number less than or equal to 3 is 3.
Thus, the sum is:
Since 144, 13, and 3 are non-consecutive Fibonacci numbers, this is the desired representation.
