Geometric Sequences and Salary Calculations

The video tutorial explains the application of geometric sequences using a practical example. Bernard, who starts with a monthly salary of 25,000 pesos, expects an annual increase of 7%. The tutorial demonstrates how to calculate his salary in the third year using the formula for geometric sequences. The common ratio is determined to be 1.07, and the calculation is performed to find Bernard's expected salary in the third year, which is 28,622.50 pesos.

What is the main topic discussed in the video?

• 7%

• 8%

How is the common ratio (r) calculated for Bernard's salary increase?

• 1.07

• 1.06

• 1.08

• 1.05

Which formula is used to calculate Bernard's salary in the third year?

• a_n = a_1 + (n-1)d

• a_n = a_1 * r^(n-1)

• a_n = a_1 * n

• a_n = a_1 / r^(n-1)

What is the result of 1.07 raised to the power of 2?

• 1.2049

• 1.1449

• 1.4049

• 1.5049

What is Bernard's expected salary in his third year?

• 28,622.50 pesos

• 27,500 pesos

• 26,000 pesos

• 30,000 pesos

What is the purpose of using a calculator in the video?

• To determine the annual increase percentage

• To calculate the power of 1.07

• To verify the common ratio

• To check the initial salary

What is the final conclusion of the video?

• Bernard's salary will increase to 30,000 pesos

• Bernard's salary will increase to 28,622.50 pesos

• Bernard's salary will decrease

• Bernard's salary will remain the same
