Question:

A team of scientists periodically measures and records to volume of sea ice in the Arctic Ocean. The scientists use the sequence shown to report the volume of ice, in cubic kilometers, every 5 years from 1980 to 2015, where begin mathsize 12px style V subscript 0 end style represents the volume of ice in 1980 and begin mathsize 12px style V subscript 1 end style represents the volume of ice in 1985.

begin mathsize 12px style V subscript 0 end style= 25,354.67

begin mathsize 12px style V subscript 1 equals V subscript n minus 1 end subscript minus 1 comma 290.12 end style

Click on each blank to complete the statements.

The variable n represents _______________. The domain for begin mathsize 12px style V subscript n end style is ___________________. begin mathsize 12px style V subscript n end style can also be written ______________.

Possible Answer:

The variable n represents the number of 5-year recordings since 1980. The domain for 

begin mathsize 12px style V subscript n end style is 0,1,2,3,4,5,6,7. begin mathsize 12px style V subscript n end style can also be written as a function.
