31

If 2+3+4=11, 3+4+5=15, 4+5+6=19, what is 7+8+9=? the pattern is x*2+(x+1)+(x+2)=x*4+3 7*2+8+9=31 the answer is 31

31 = (7*2)+8+9

If 2,6=5 4,9=7 6,11=8 8,15=11 then 12,18=?

IF 1,3,3=5 9,7,4=8 11,14,10=15 20,16,12=18 Than 3,6,7=?

If the following is true, can you find the value of (4 + 9)?

7 + 7 = 2 8 + 8 = 4 8 + 5 = 1 6 + 9 = 3 10 + 11 = 9

If 6 + 4 = 210 9 + 2 = 711 8 + 5 = 313 5 + 2 = 37 7 + 6 = 113 9 + 8 = 117 10 + 6 = 416 15 + 3 = 1218 Then ?? + ?? = 123

If 2+4+6=19, 3+6+9=43, 4+6+8=53 then 9+5+3=?
