An arithmetic sequence has first term a₁ = 7 and difference d = 4. Find the 15th term a₁₅.
Direct Answer: Arithmetic Progression Term is defined by: 63. a_n = a₁ + (n - 1)d => a₁₅ = 7 + (14) · 4 = 7 + 56 = 63.
Detailed Step-by-Step Explanation:
a_n = a₁ + (n - 1)d => a₁₅ = 7 + (14) · 4 = 7 + 56 = 63.
