Arithmetic Sequence Definition: Initial term is a1=5 and recursive formula is an=an−1+12. This is an arithmetic sequence with a common difference of 12.
Explicit Formula: The explicit formula for an arithmetic sequence is an=a1+d(n−1), where d is the common difference.
Substitution: Substitute a1=5 and d=12 into the formula: an=5+12(n−1).
Simplification: Simplify the formula: an=5+12n−12.
Combining Terms: Combine like terms: an=12n−7.
