3.12 Arithmetic Sequence Practice

Front

Identify a₁ and d for the sequence
-5, -2, 1, 4, ...

Back

a₁ = -5 and d = 3

Front

Write the recursive rule for the arithmetic sequence: 82, 76, 70, 64, ...

Back

a₁= 82; a_n = a_n-1 - 6

Front

Write the explicit rule for the arithmetic sequence
12, 10, 8, 6, ...

Back

a_n = -2n + 14

Front

Find the 32nd term of this sequence.
9, 4, -1, -6, -11, ...

Back

Front

Identify the rule as recursive or explicit, then find the first 4 terms of the sequence: a₁ = 100; aₙ = aₙ₋₁ - 8

Back

Recursive; 100, 92, 84, 76

Front
