What Comes Next in the Sequence: If 5 # 4 # 3 # 9 = 4215 Then 7 # 2 # 7 # 4 = ?

Answer:

The equation is solved in this way.

If we take the equation as A # B # C # D  then;

first digit = first digit of the product of (A x D)

second digit = second digit of the product of ( B x C)

third digit = first digit of the product of ( B x C)

fourth digit = second digit of the product of (A x D)

This fits in all the 3 equations

So now we can get value of fourth equation;

7 # 2 # 7 # 4;

First let us find (A x D) and B x C)

A x D = 7 x 4 = 28

B x C = 2 x 7 = 14

So answer = 2418
