$Which term of the sequence 5, 8, 11, 14, \dots is 32 ?$

A. $8 th$
B. $9 th$
C. $10 th$
D. $11 th$

Show correct answer & step-by-step solution

Correct answer: C — $10 th$

Solution

Using the formula a_{n} = a + (n - 1) d, we set $32 = 5 + (n-1)3$. Solving for n gives $27 = (n-1)3$, so n - 1 = 9, which means n = 10 .
