Mean of a SequenceDate: 06/09/2002 at 12:55:10 From: Ana Subject: What is the arithmetic mean of the first one thousand positive odd numbers? I've tried to figure out the answer in many different ways, like finding the mean of the first 5 odd numbers, and the next 5 odd numbers, to see if there is a pattern, but I get very stuck. Thanks for trying to help. Date: 06/09/2002 at 19:27:07 From: Doctor Ian Subject: Re: What is the arithmetic mean of the first one thousand positive odd numbers? Hi Ana, Starting small is exactly the right approach: 1 mean = 1 1 3 mean = 2 1 3 5 mean = 3 1 3 5 7 mean = 4 1 3 5 7 9 mean = 5 1 3 5 7 9 11 mean = 6 Do you see a pattern now? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ Date: 06/12/2002 at 20:54:40 From: Ana Subject: Thank you (What is the arithmetic mean of the first one thousand positive odd numbers?)
