If 2,6=5 4,9=7 6,11=8 8,15=11 then 12,18=?
18 - half of 12 =12 so 12 is the answer
Answer = 12 a,b = b - a/2 2,6=5 -> 6 - 2/2 = 5 4,9=7 -> 9 - 4/2 = 7 6,11=8 -> 11 - 6/2 = 8 8,15=11 -> 15 - 8/2 = 11 then 12,18= -> 18 - 12/2 = 12
2+6-3=5 4+9-6=7 6+11-9=8 8+15-12=11 12+18-15=15 The answer is 15.
Ans:11
2,6=5----> 5+2=7-1=6(ans+1st num)-(2nd num) 4,9=7----> 7+4=11-2=9 6,11=8-> 8+6=14-3=11 8,15=11-->11+8=19-4=15
12,18=11--->11+12=23-5=18
IF 1,3,3=5 9,7,4=8 11,14,10=15 20,16,12=18 Than 3,6,7=?
