    It is 6 Because 15 is a even number and 6 is an odd number and that’s how you do it the second one is 10 because they all start with 0 like 20,50,60,70,80 and90 and that’s how you do it.bronze
    Silver
    I know why because 150 is not greater than 700 the second one is that are 406 because if you had 206 you need to double it so it can be 406.

    And that’s how you do
