In this puzzle you will have to do a little math. You need to figur out the pattern each column is following.
The series in the first column goes like this:
1+1=2 then 2+1=3 then 3+1=4. So logically, 4+1=5. So 5 is the missing number.
The series in the second column goes like this:
The sum of 4 and 8 is 12. Then sum of 8 and 12 is 20. So the missing number would be 20+12=32.
The series in the third column goes like this:
1^3-1=0, then 2^3-1=7, then 3^3-1=26, then 4^3-1=63, so 5^3-1=124
The series in the last column goes like this:
576-400=176. Then 400-256=144. Then 256-144=112. The difference is getting smaller by 32. So the next number will be 144-(112-32)=64.
Now solve the equation: 5 * 32 =160
and 124+64=188.
press the keypad and input 160188. This should unlock the bars and you can proceed to the next level.
