Step-by-step explanation:

Given : Series 3, 1, 11, 25, 83, ?​

To find : The missing number in the following series ?

Solution :

We notice the pattern in the series which is as follow :

$\frac{11-3\times 3}{2}=\frac{2}{2} =1$

$\frac{25-3\times 1}{2}=\frac{22}{2} =11$

$\frac{83-3\times 11}{2}=\frac{50}{2} =25$

According to it let the missing number be 'x'.

$\frac{x-3\times 25}{2}=83$

$x-75=166$

$x=166+75$

$x=241$

The missing number is 241.
