Answer:

b) 10 to 20

Step-by-step explanation:

You have to multiply each of the given numbers by 4, and add 8 to that result.

So:

  • 0*4+8  = 8
  • 10*4+8 = 48
  • 20*4+8 = 88
  • 30*4+8 = 128
  • 40*4+8 = 168

And 60 is between the result of 10 and 20, so that's the interval you have to select.

The correct answer is b) 10 to 20
