Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.153 Determine the nth Term from a Pattern or Table skill assessments:

Problem 1Difficulty: Mastery
The pattern lists a_1 through a_4 as 1, 3, 8, 17. What is the explicit rule for a_n?
Aa_n = n2 + 2n
Ba_n = (n - 1)2 + 2n
Ca_n = (n + 1)2 + 2^(n-1)
Da_n = (n - 1)2 + 2^(n-1)
Solution & Explanation:Both parts are indexed from n=1, so the exponent and square each use n - 1. Substituting into a_n = (n - 1)2 + 2^(n-1) confirms the table: n=1 gives 1; n=2 gives 3; n=3 gives 8; n=4 gives 17.
Problem 2Difficulty: Mastery
For the sequence table n | 1|2|3|4; a_n | 5|13|35|97, choose the explicit nth-term expression.
Aa_n = 5n
Ba_n = 2^(n+1) + 3^(n-1)
Ca_n = 2n + 3n
Da_n = n2 + 3n
Solution & Explanation:Each output is the sum of a power of 2 and a power of 3. Substituting into a_n = 2n + 3n confirms the table: n=1 gives 5; n=2 gives 13; n=3 gives 35; n=4 gives 97.
Problem 3Difficulty: Mastery
A sequence begins 1, 3, 12, 60 for n = 1 to 4. Select the nth-term formula.
Aa_n = n!/2
Ba_n = (n + 1)!/2
Ca_n = (n + 1)!
Da_n = 2(n + 1)!
Solution & Explanation:The terms grow factorially rather than by a fixed difference or ratio. Substituting into a_n = (n + 1)!/2 confirms the table: n=1 gives 1; n=2 gives 3; n=3 gives 12; n=4 gives 60.
