Select the set of numbers from the given options which is NOT similar to the given set.
(15, 112, 13)

Given Set : (15, 112, 13)

The pattern followed here is : 

• (The sum of first and third number)$$\times\ $$4 = Second number

Lets check option wise, 

Option A : (11, 76, 8)

$$\therefore\ \left(11+8\right)\times\ 4=76$$

Following the pattern.

Option B : (17, 102, 9)

$$\therefore\ \left(17+9\right)\times\ 4=104$$

Not following the pattern.

Option C : (13, 96, 11)

$$\therefore\ \left(13+11\right)\times\ 4=96$$

Following the pattern.

Option D : (12, 72, 6)

$$\therefore\ \left(12+6\right)\times\ 4=72$$

Following the pattern.

So, Option B is NOT similar to the given set. 

Hence, Option B is correct.
