Here is a possible solution for numbers 1-5:

Left side - 1 + 4 + 5 = 10
Right side - 5 + 3 + 2 = 10

We then moved on to 2-6:

Left side - 5 + 2 + 6 = 13
Right side - 6 + 3 + 4 = 13

Then onto 16-20:

Left side - 18 + 17 + 20 = 55
Right side - 20 + 16 + 19 = 55

Finally, we looked at 103-107:

Left side - 104 + 107 + 103 = 314
Right side - 103 + 105 + 106 = 314
