Question

The first three terms of a Fibonacci sequence are n 3n 4n find the sixth term I FB the sequence

Answer 1

Answer:

18n

Step-by-step explanation:

In the Fibonacci sequence In mathematics, the Fibonacci numbers, commonly denoted $Fn$, form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1.

Given data

First term= n

second term = 3n

third term = 4n

According to Fibonacci sequence the fourth term is

$F4= F2 + F3\\F4=3n+ 4n= 7n$

the Fifth term is

$F5= f3 + f4\\f5= 4n+7n= 11n$

hence  the sixth term is

$F6= F4+F5\\ F6= 7n+11n= 18n$
