Best ResponseYou've already chosen the best response.0well, all this question is asking is "what consecutive odd numbers add up to 21? and what is the largest digit?"

Best ResponseYou've already chosen the best response.0for instance, 3+5+7 does not equal 21, therefore it can't be 7 7+9+11 does not equal 21, so it can't be 11 however, there is a sequence of odd numbers that includes 7, that equals 21.
