What is the answer for the below puzzle 1,5,8=76, 2,7,3=25, 3,4,9=89, 4,5,7=69, then 5,3,8=?
With a little inspection the series x,y,z = s
can be observed to have s = (z * 10) - (y - x)
For the first equation s = (8 * 10) - (5 - 1) = 76
Similarly for the second equation s = (3 * 10) - (7 - 2) = 25 …. and so on.
Therefore for the last equation, s = (8 * 10) - (3 - 5) = 80 - (-3) = 82.
Thus 5,3,8=82.
alternately the series can also be represented as
s = (z * 10) - |(y - x)| where the | | denote ‘absolute value’ or the positive difference between. y and x, in which case, for the last equation in the series, s = 80 - |3 - 5| = 80 - 2= 78.
