If num == 0 then return 0.Since Fibonacci of 0 th term is 0.; If num == 1 then return 1.Since Fibonacci of 1 st term is 1.; If num > 1 then return fibo(num - 1) + fibo(n-2).Since Fibonacci of a term is sum of previous two terms. By "the nth term" of a sequence we mean an expression that will allow us to calculate the term that is in the nth position of the sequence. Finding the nth term of a linear sequence Sometimes, rather than finding the next number in a linear sequence, you want to work out the \({41}^{st}\) number, or the \({110}^{th}\) number. The complete sequence from terms one through six is shown below. The first term is , and the second term is The third term is Thus, has been added to in order to obtain , and has been added to in order to obtain This shows that is added to each preceding term in the sequence in order to obtain the next term. = a n = a + (n − 1) d. a n = 63 + (n − 1) 2 = 63 + 2n − 2. a n = 61 + 2n (1). mathhelp@mathportal.org. a n = a 1 + ( n – 1) x d. a 1 = 5, d = 5. a n = 5 + ( n – 1) x 5. a n = 5 + 5n – 5. a n = 5n.
