This question has been asked as a puzzle in a forum of an online game, but I coudn't solve it neither any of the members of the forum, so I asked for help here.
giving this sequence of numbers
1 > 170
2 > 344
3 > 520
4 > 698
5 > 875
6 > 1052
8 > x
16 > 2811
20 > y
What would be x and y based on that sequence ?
the moderator has given us a hint after 2 days , but we still can't figure it out, the Hint is:
based on
a > b
c > d
calculating the number $a*d - c*b$ for each row should give us a clue.
I noticed that $d = (c*b + z) / a$
and $z = a*d - c*b$
The problem is that d and z both are unknowns and the 2 formulas are the same so I can't figure out 2 unknowns in the same formula.
How to figure out x and y ?
Using the hint,
$$x=1405,y=3514$$ makes a symmetric pattern.
