Question

What is the 11th term of the A.P. \(2,\,5,\,8,\,11,\,\ldots\)?

• A. \(24\)
• B. \(30\)
• C. \(32\)
• D. \(14\)

Hint:

The \(n\)th term of an A.P. is given by \(a+(n-1)d\).

Answer 1

The Correct Option is C

Step 1: Identify terms. First term \(a=2\), common difference \(d=3\).
Step 2: Use formula.
\[ a_{n} = a+(n-1)d \]
Step 3: Substitute.
\[ a_{11}=2+(11-1)\cdot 3=2+30=32 \]
