Question

Choose a number from the options that will continue the same pattern replace the question mark in the given series.
$13,25,52,101,?$

• A. $201$
• B. $203$
• C. $205$
• D. $206$

Answer 1

The correct option is D $206$

Given series is: $13,25,52,101,?$
Here, we have,
$25=13\times 2-1$
$52=25\times 2+2$
$101=52\times 2-3$

Now, let the missing number be $y$.
$y=101\times 2+4=206$

Hence, option D.
