There's no equation to solve, until you tell us
what that expression is equal to.
Thee correlation factor formula for two variables is
(r) =[ nΣxy – (Σx)(Σy) / Sqrt([nΣx^2 – (Σx)^2][nΣy^2 – (Σy)^2])].
A). as per the formula the correlation factor for the given data is 0.94.
B). the month of September has the highest correlation as 0.94 is much closer to 1 than 0.89.( note: 1 denotes the perfect correlation and 0 denotes no correlation at all)

We try the all of the numbers until we find it
1*1=1
2*2=4
3*3=9
4*4=16
5*5=25
6*6=36
7*7=49
So the answer is 7
