Tag! Find out the wrong number in the given sequence of numbers. Well, I tried to see if this is a geometric sequence but it is not, because I don't see there is a common ratio among the numbers listed. Also, I tried the arithmetic sequence, and found no common difference here, Any lead will be appreciated, thanks in advance!.

Replace 47 with 46 and then it's a quadratic sequence. Verified by iterated differences: zero order (original sequence): 8,13,21,32,46,63,83 first order: 5,8,11,14,17,20 second order: 3,3,3,3,3 |

Hello, I have one question. I have been trying to find the nth number for this quadratic sequence but I am not getting anywhere, could you help? I know that the first difference is and that the second difference is know this is a quadratic sequence because the second difference is the same, so it should start off at I have seen videos where the second difference is even. then the tutor says to have the number and put it in front of let's suppose the second difference is then it would be you see, but in this case the second difference is 3 ad when when take the half of does not work how can go about finding the nth term when the second difference is an odd number? thanks for any help |

> when i take the half of 3(1.5) does not work It's sad that you don't read the postings. I repeat: |

when when and so forth and so on until, Thanks, Just one doubt . this is a set formula or you come up with it. I have not seen it in the videos have watched I know, but why . the 2 diivides everytihng just in case it doesn;t show properly I will appreciate your answer. thanks a lot for such a good support. |

A direct way to obtain the formula uses the first elements of each row of the iterated differences, i.e. "8 , 5 , 3": See en.wikipedia.org/wiki/Newton_polynomial#Application for details. |
