A bouncing ball issue reaches its next peak as some fraction or multiple of the previous peak, so, that'd make it a
geometric sequence.
so, let's take a peek, 27, 18, 12
now, to get the
common factor from a geometric sequence, since it's just a multiplier, if you divide any of the terms by the term before it, the quotient is then the common factor, let's do so with hmm say 12 and 18, 12/18 = 2/3 <---- the common factor, you can check if you so wish with 18/27.
and the first term is of course, 27.
Dunnow what the formula is for
combinations vs permutations
combos, the order does matter and you can repeat
permutations, the order doesn't matter and once you use something, you can't repeate it
what you do is
(number of choices)^(number of slots y ou have to fill)
in this case
number of choices is 3 (3 fllavors)
number of slots=2 since 2 toppings
3^2=9
9 choices
chocolate-carmael
chocolate-strawberry
chocolate-chocolate
strawberry-carmael
strawberry-chocolate
strawberry-strawberry
carmael-chocolate
carmael-strawberry
carmael-carmael
9 choices
2 and 28 do belong together 4 and 14 do not belong together because there is nothing to multiply 4 by to get 14.6 and 9 do not belong together because as I said last time there is nothing to multiply etc........
The two purple ones are the parallelograms
Hope this helps! ^^
