To find the amount left after 1 hour, 3 hours, and 4 hours.
The amount left after 1 hour, 3 hours and 4 hours are
Given information:
The table of geometric sequence representing the amount of the isotope initially and after 2 hours as 1244 and 346 respectively.
Calculation:
The nth term of the sequence for the amount left can be given as
Since
The nth term of the sequence can be written as
Now, find the amount left after 1 hour, 3 hours and 4 hours.
Therefore, the amount left after 1 hour, 3 hours and 4 hours are
