write 160 as the sum  of a nonconsecutive Fibonacci numbers

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:  
  \( 160 - 144 = 16 \)

- The largest Fibonacci number less than or equal to 16 is **13**.
- Subtracting 13 from 16 gives:  
  \( 16 - 13 = 3 \)

- The largest Fibonacci number less than or equal to 3 is **3**.

Thus, the sum is:
\[
160 = 144 + 13 + 3
\]

Since 144, 13, and 3 are non-consecutive Fibonacci numbers, this is the desired representation.
