Question

Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.

$6,12,21,?,48$

• A. $33$
• B. $38$
• C. $40$
• D. $45$

Answer 1

The correct option is A $33$

$6,12,21,?,48$
The given series is $+6,+9,+12,+\mathrm{15....}$
Thus, each term is added with a number increased by $3$ from the previous added number.
Hence, missing term = $21+12=33$
