Question

Find the missing character, if a certain rule is followed in the figure.

• A. $190$
• B. $221$
• C. $236$
• D. $255$

Answer 1

Answer: (D)

$255$

On observing the figure carefully,

The pattern we get is :
$7\times 2+1=15$
$15\times 2+1=31$
$31\times 2+1=63$
$63\times 2+1=127$
$\therefore 127\times 2+1=255$.

Hence, the missing character is : $255$
