you basically have to times it by 3 so
2:7
4:14
6:21
the answer would be 6 tablespoons of sugar to 21 tablespoons of flour
Let's start from what we know.

Note that:

(sign of last term will be + when n is even and - when n is odd).
Sum is finite so we can split it into two sums, first

with only positive trems (squares of even numbers) and second

with negative (squares of odd numbers). So:

And now the proof.
1) n is even.
In this case, both

and

have

terms. For example if n=8 then:

Generally, there will be:

Now, calculate our sum:



So in this case we prove, that:

2) n is odd.
Here,

has more terms than

. For example if n=7 then:

So there is

terms in

,

terms in

and:

Now, we can calculate our sum:




We consider all possible n so we prove that:

Answer:
672
Step-by-step explanation:
12 * 12 = 144
144* 14 = 2016
2016 / 3 = 672.
