Answer:

  • 60, 72, 86.4, 103.68, 124.416, ...

Step-by-step explanation:

Given sequence:

  • 60, 72, ...

The rule is adding 20%

Adding 20% is converted to common ratio:

  • x + 20% =
  • 120% of x =
  • 1.2x

The sequence is the GP with common ratio of 1.2:

  • 60, 72, 72*1.2= 86.4 , 72*1.2² = 103.68 , 72*1.2³ = 124.416
