Arithmetic Sequences - Practice/Group Activity (70 problems)

This is a resource on arithmetic sequences having 14 practice pages and containing a total of 70 problems arranged by topic/type and difficulty level. 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 difference (Level 1)
• the number of terms (Level 1)
• the first term and the common difference 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 nth term and Sn (Level 1)
• the first term 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 d -
• the nth term and d
• n and nth term
• the first term and d
• 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.
