Let Fib (n) be the nth term of the Fibonacci sequence with Fib (1) = 1, Fib (2) = 1, Fib (3) = 2 what is Fib (1) + Fib (2) + Fib (3) + Fib (4) + Fib (5)?

Sagot :

Answer:

Fibonacci sequence or Fibonacci numbers are a group of number/terms in which each number is the sum of the two preceding ones. This goes as follows:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... ,∞

Fib(1) + Fib(2) + Fib(3) + Fib(4) + Fib(5) = ?

= 1 + 1 + 2 + 3 + 5 (because the first term (0) is written as Fib(0).)

= 12

Hope this helps. ^^
