16-7 + (4) = 29-16, 29-16 + (4)= 46-29, 46-29 + (4) = '67'-46
26.Add successive odd numbers to get the next number in the list:1+1=2, 2+3=5, 5+5=10, 10+7=17, 17+9=26. The number following 26 would be 37: 26+11=37.
The next number in the series is 67.
7+4=11 11+8=19 19+16=35 35+32=67 so the next no. is 67..............
67 7 + 4 = 11 11 + 8 = 19 19 + 16 = 35 35 + 32 = 67 67 + 64 = 131 ...
