SpletAnswer: The sequence is increasing by 3 each time so compare the sequence with the multiples of 3 (3,6,9,12,15...). You will then need to minus 1 from the multiples of 3 to give the numbers in the sequence. So the nth term is 3n - 1. Question: What is the nth term for the sequence 7,9,11,13,15? Answer: Its going up in twos so the first term is 2n. SpletHow do you find the nth term in a sequence? For example : 3, 5, 7, 9, 11, is an arithmetic progression where d = 2. The nth term of this sequence is 2n + 1 . In general, the nth term of an arithmetic progression, with first term a and common difference d, is: a + ( n - 1)d .

SpletWe are given A₀ = 3 and the formula for A_n = 1/ (A_ (n-1)) + 1 So to find A₁, use the formula, A₁ = 1/ (A₁-₁)) + 1 = 1/A₀+1, then A₂=1/ (A₂-₁) + 1 = 1/A₁ +1, and A₃=1/ (A₃_₁) +1=1/A₂+1. I think you can take it from here by substitute in what A₂, A₁, and A₀ are.

SpletThe numbers in the sequence are always 2 less than the 6 times table so we "adjust" our rule by subtracting 2. Now putting this together gives us: n th term = 6n - 2. c) Now we know the n th term = 6n - 2 we just need to substitute n = 50 in order to find the 50 th term of the sequence.
