Worksheet: Applications on Geometric Sequences

In this worksheet, we will practice solving real-world applications of geometric sequences, where we will find the common ratio, the nth term explicit formula, and the order and value of a specific sequence term.

Q1:

After falling, a rubber ball bounces back to 1 4 of its previous height. Given that the ball fell from a height of 653 cm above the ground, find, to the nearest integer, the height it would reach after its second bounce.

Q2:

The population of a city is now 844,501 and increases at a constant rate of 1 2 % per year. Find the population after 8 years giving the answer to the nearest integer.

Q3:

Q4:

The value of a brand-new car which cost 498,300 LE decreases at a rate of 1 5 % every year. Find the price of the car after 8 years giving the answer to the nearest pound.

Q5:
