Best ResponseYou've already chosen the best response.0Here's the question: The first 50 terms of a pattern sum to 2000. a) Describe the pattern. b) Describe how you found the sum. c) Give the 100th term of the pattern. d) List all the patterns that you found.

Best ResponseYou've already chosen the best response.0well, there are 2 sequence summations that we can use; and arithmatic and a geometric

Best ResponseYou've already chosen the best response.0we haven't been doing geometry, so it's probably the arithmatic

Best ResponseYou've already chosen the best response.0lets do arith then :) \[\frac{50(a_1+a_{50})}{2}=2000\] \[{25(a_1+a_{50})}{}=2000\] \[{a_1+a_{50}}{}=2000/25\] \[{a_1+a_{50}}{}=80\] sound good?

Best ResponseYou've already chosen the best response.0ok, thanks for your help. so then we could set any number as the first term and go from there?

Best ResponseYou've already chosen the best response.0correct; choose any 2 numbers that add up to 80; and work in the summation rule for the rest of it to get the details of the common difference
