The hundred thousand column is the 6th column so you look at the 5th number and round
9 rounds up to 0

Answer:
Option a.) an = -4(-3)^(n-1)
It is tree times more value or 15 not sure
One possible way:
-86+(4*12)=-38
-86 is the number where the diver is. 86 feet below the surface.
4*12 is the total number of feet he has ascended in 12 minutes.
Because he is ascending, so you add 4*12 (or 48) to -86.
The answer is -38, meaning he's 38 feet below the surface.
The diver is now 38 feet below the surface.
Hope this helps.
