Answer 6

Look at your answers and think which of these if you add the three numbers following to it, will give you a sum of 74?
So for example, to check the first option, 16, you'd take the three numbers that come after 16 also and add them all together.
Does 16 + 17 + 18 + 19 = 74?

Answer 7

it equals 70

Answer 8

Right so we know it's not A. :P Try the same thing for the other options and see which one does give you a sum of 74.
Is it B? 17 + 18 + 19 + 20 = ?
