The arithmetic sequence formula should help you An= A1+ (n-1)d or An= a + d(n−1) An= the term that you want to find. A1 = first term in the list of ordered numbers n = the term position (ex: for 5th term, n = 5 ) d = common difference of any pair of consecutive or adjacent numbers So, looking the 4 choices you have the only one that follow the sequence of the formula is C I believe the one you choose is Fibonacci sequence. There different number of sequences: 1- arithmetic sequence 2- geometry sequence 3- Fibonacci sequence Each of that sequences have their own formula. So, the answer it might be C Hope that help you
The formula for the Arithmetic is: An = A1 + F x ( n- 1) I believe answer is C Because the one you chose is
