In such puzzles, first we have to find out the logic behind the sequence, so that the value mentioned can be derived mathematically.
Let us see the logic behind this puzzle. The puzzle is following a strange sequence. First the difference of middle number and first number is subtracted. Then multiplication by 10 in last number of the set to be done, then from the product, the difference of middle number and first number to be substracted to derive the final value of the set.
For illustration
Let m, n, o = p. Then first subtract m from n = (n - m) then o × 10 - value from n - m to get p
Accordingly, we have to proceed by this logic starting with first set.
1, 5, 8=76
5 – 1 = 4
8 × 10 - 4 = 76
–—
2, 7, 3 = 25
7 - 2 = 5
3 × 10 - 5 = 25
—-
3, 4, 9 = 89
4 - 3 = 1
9 × 10- 1 = 89
——
4, 5, 7 = 69
5 - 4 = 1
7 × 10 - 1 = 69
——
5, 3, 8 = ??
3 - 5 = - 2
8 × 10-(-2)= 82
