Question
Quote:
77. ( 19 [ 64 ] 26 ) ( 17 [ 52 ] 18 ) ( 25 [ ___ ] 5 )
(19+26)+19=64: (17+18)+18=52: (25+15)+25=65
In the last set you have used the number 15 instead of 5. The answer is therefore 55

Actually I think I went the wrong way on the second one, as well:
Pattern is, I think
(Number before+Number after)+Number
before as in the first one, so
(17+18)+17=52: (25+5)+25=55
or just (Number before*2)+Number after?
For the first q, the pattern is: ()a*b - b, where a is the number before and b the number after the brackets, and so on.
