Specific objective: To recognise a G.P. Activity 11 – Content (CW6) Recognising a G.P. Description: This activity worksheet is designed to explore the geometric progressions. Execution: Students will be asked to investigate the given sequences and separate G.P. by finding the ratios of two consecutive terms. Parameters for assessment: Able to find the ratio of consecutive terms Able to recognise a G.P. Able to tell whether a given sequence is a G.P. or not Able to write a G.P. with given first term and common ratio 21
Activity 12 – Content (CW7) General Terms of a G.P. Specific objective: To write the nth term of a G.P. Description: Through this activity sheet students would be able to find the formula for general term of a G.P. as an = ar n-1 Execution: Ask the students to observe the pattern given in the worksheet. Motivate them to observe the pattern and generate nth term. Using the formula for nth term, ask them to find specified terms like 20 th term, 100 th term etc. Parameters for assessment: Able to write the formula for nth term of a G.P. 22
