Best ResponseYou've already chosen the best response.1okay so starts from 5 so we know that 5 is a constant which is added on... now try writing "four less than twice the previous line" as an expression. Let l be the number of marbles in the previous line

Best ResponseYou've already chosen the best response.1I think the easiest way to do it is to follow the pattern... because I can't find any AP/GP or linear relationship, though there probably is a bette way to do it but anyway this is what I would use... so line 1: 5 marbles (we are told this) line 2: 2(5) 4 = 6 line 3: 2(6)  4 : 8 and so on.... till you get to line 6

Best ResponseYou've already chosen the best response.0the rule is 2*n  4 where n is the number of marks in the previous line if you count the number of marks in line 4, you get 12 to find the number of marks in line 5, do 2*12  4 that simplifies to 20 now find the number of marks in line 6: 2*20  4 = 404= 36
