Final answer:
To finish the pattern using the rule of adding 75 and 20, the missing numbers are 95, 170, and 245.
Step-by-step explanation:
To finish the pattern using the given rule of adding 75 and 20, we need to determine the missing three numbers. Starting with the given numbers, 20 and the next number is 20 + 75 = 95. Adding 75 again, we get the next number as 95 + 75 = 170. Finally, adding 75 one more time, the last number in the pattern is 170 + 75 = 245.
