Question

type the missing numbers.
0 60 80 100
submit

Explanation:

Step1: Find the interval between marks

Between 60 and 80: \( 80 - 60 = 20 \). Between 80 and 100: \( 100 - 80 = 20 \). So each interval is 20.

Step2: Find the left of 0

Left of 0: \( 0 - 20 = -20 \).

Step3: Find between 0 and 60

First after 0: \( 0 + 20 = 20 \). Second after 0: \( 20 + 20 = 40 \).

Answer:

-20, 20, 40
