To calculate Fibonacci extensions in Ruby, you can use the following steps:

- Define a method that calculates the Fibonacci sequence up to a certain number of terms. For example:

1 2 3 4 5 6 7 |
def fibonacci(n) fib = [0, 1] (2..n).each do |i| fib << fib[i-1] + fib[i-2] end return fib end |

- Call the method and store the Fibonacci sequence in a variable:

```
1
``` |
fib_sequence = fibonacci(10) |

- To calculate the Fibonacci extensions, multiply the last Fibonacci number by a specified extension factor. For example, to calculate the 1.618 Fibonacci extension:

1 2 |
extension = fib_sequence.last * 1.618 puts "1.618 Fibonacci extension: #{extension}" |

- Repeat step 3 to calculate other Fibonacci extensions, such as the 2.618 or 4.236 extensions.

By following these steps, you can easily calculate Fibonacci extensions in Ruby.
