Final answer:
If the pattern is to multiply the number of tanks by 8, the table values will increase by a factor of 8.
Step-by-step explanation:
If the pattern is to multiply the number of tanks by 8, the table would change by each value being multiplied by 8. For example, if the original table had the values 2, 4, 6, and 8, the new table would have the values 16, 32, 48, and 64 respectively. This means that each value in the table would increase by a factor of 8.
