Correct answer: B
Pattern: each term is obtained by adding successive powers to the previous term (the differences are 1^1, 2^2, 3^3, 4^2, 5^3).
Step 1: 14 + 1^1 = 14 + 1 = 15
Step 2: 15 + 2^2 = 15 + 4 = 19
Step 3: 19 + 3^3 = 19 + 27 = 46
Step 4: 46 + 4^2 = 46 + 16 = 62
Step 5: 62 + 5^3 = 62 + 125 = 187
