Geometric Sequences & Series -Practice (70 classified problems)

These are 14 practice pages on geometric sequences. Students will use the explicit formula and the formula for the sum of the first n terms.

➤ Using the explicit formula students will have to find

• the nth term (problems Level 1)
• the first term (problems Level 1)
• the common ratio (Level 1)
• the number of terms (Level 1)
• the first term and the common ratio solving systems of two equations (Level 2)

➤ Using the formula for the sum of the first nth terms students will have to find

• the sum of the first nth terms (problems Level 1)
• the first term and Sn (Level 1)
• the common ratio and Sn (Level 1)
• the number of terms and Sn (Level 1)

➣ When given Sn (problems level 2) students will have to calculate

• n and r
• the nth term and r
• n and nth term
• the first term and r
• the first and nth terms
• n and first term

The practice sheets can be used for independent and extra practice, enrichment, as a group activity( groups of 2, 3 and/or 4), homework and even as an assessment.

Answer keys are included.
