Question

given: fib(15)=610 and fib(18)= 2584 what is fib(25)?​

Answer 1

Given:

Given, fib(15) = 610 and fib(18) = 2584.

To find:

We need to find the value of fib(25).

Solution:

Given that, fib(15) = 610 and fib(18) = 2584.

fib is nothing both Fibonacci numbers.

The Fibonacci numbers are found by adding the two numbers before it.

• The 0th term in Fibonacci series is fib(0) = 0.
• The 1st term in Fibonacci series is fib(1) = 1.
• The 2nd term in Fibonacci series is fib(2) = 1.
• The 3rd term in Fibonacci series is fib(3) = 2.
• The 4th term in Fibonacci series is fib(4) = 3.
• The 5th term in Fibonacci series is fib(5) = 5.
• The 6th term in Fibonacci series is fib(6) = 8.
• The 7th term in Fibonacci series is fib(7) = 13.
• The 8th term in Fibonacci series is fib(8) = 21.
• The 9th term in Fibonacci series is fib(9) = 34.
• The 10th term in Fibonacci series is fib(10) = 55.
• The 11th term in Fibonacci series is fib(11) = 89.
• The 12th term in Fibonacci series is fib(12) = 144.
• The 13th term in Fibonacci series is fib(13) = 233.
• The 14th term in Fibonacci series is fib(14) = 377.
• The 15th term in Fibonacci series is fib(15) = 610.
• The 16th term in Fibonacci series is fib(16) = 987.
• The 17th term in Fibonacci series is fib(17) = 1597.
• The 18th term in Fibonacci series is fib(18) = 2584.
• The 19th term in Fibonacci series is fib(19) = 4181.
• The 20th term in Fibonacci series is fib(20) = 6765.
• The 21st term in Fibonacci series is fib(21) = 10946.
• The 22nd term in Fibonacci series is fib(22) = 17711.
• The 23rd term in Fibonacci series is fib(23) = 28657.
• The 24th term in Fibonacci series is fib(24) = 46368.
