Answer:
20
Step-by-step explanation:
Well consecutive numbers mean that the 3 numbers will follow each other in smallest to largest.
Example : 6, 7, 8 or 6,34,87
Non-Example : 7, 9, 6
As long as the number is greater than the one before it they are consecutive.
Following this rule I have come up with the numbers :
10, 12, 20
These three numbers are consecutive and equal to 42.
Now to find the largest number in this set just look at the greatest value which would be 20.
I don't have an entire explanation for this as I just did it in my head but I do hope it is correct.
I hope this helps! :)

The company lost a little less than $100.
Since the number is negative, we know that they lost money. If it was positive, it would've indicated they made money. If they made no money, they would've broken even. This narrows it down to the last two. Since 98 < 100, we know they lost less than $100, which leaves us with the last one.
