Given:

The series of numbers is 13, 15, 19, 27. ?

To Find:

The correct alternative to replace the question mark in the given number series 13, 15, 19, 27,?

Explanation:

The following points are necessary for solving this problem.

• Every correct series forms a systematic pattern.
• The difference between the successive terms is either a constant or forms a pattern.

Step 1 of 3

From the terms of the given series, deduce the differences in the following way.

$15-13=2\\19-15=4\\27-19=8$

Step 2 of 3

Inspecting the differences, the following is deduced.

$2=2^1\\4=2^2\\8=2^3$

Step 3 of 3

So, going by the above sequence, the next difference is

$=2^4=16$

Thus, the next number is

$=27+16\\=43$

Therefore, option 3 is the required correct answer, because 43 follows 27 in the number series $13, 15, 19, 27, ...$.
