What is a14 of the sequence 2,11,20,…?
1 answer:
Answer:
119
Step-by-step explanation:
Since the terms have a common difference (d) between consecutive terms then the terms are an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
a₁ = 2 and d = 20 - 11 = 11 - 2 = 9, hence
= 2 + (13 × 9) = 2 + 117 = 119
