The question asks you identify the pattern and find the missing character.
I have been trying to solve this problem from a long time but I have not found any pattern till now. Please help!!

$\begingroup$ Hi Divya, don't forget to state in the puzzle where you got this from - otherwise your question might end up being closed due to not having the correct attribution (it's part of PSE's anti-plagiarism policy). Is it another coaching DPP like your last puzzle? If so, do state it in the text (if not, state where it is from instead...). Thanks! $\endgroup$– StivNov 12, 2019 at 8:58

1$\begingroup$ Maybe this one is another mistyped question, the answer is 16 (three numbers added minus the lower number) :P $\endgroup$– balazs.comNov 12, 2019 at 9:04

$\begingroup$ This question is not wrong. Yes, 16 makes a pattern but the correct answer is one of the numbers given in options. $\endgroup$– Divya Prakash SinhaNov 12, 2019 at 9:57

Since:
15+3=18
7+9+2=18
and
26+18=44
25+8+11=44
Then:
16+4=20
5+9+6=20
So the number is:
16

$\begingroup$ Simpler put, 2+9+7-3 = 15, 11+8+25-18 = 26 => 9+6+5-4 = 16 $\endgroup$ Dec 14, 2019 at 22:06

$\begingroup$ it is A+B+C= center+D= clockwise A=2 is 9 oclock 2+9+7=18 15+3=18 $\endgroup$ Dec 16, 2019 at 0:31

It's probably a typo
Given that there are only 2 examples to work with, it must be a very simple formula. Usually the formula uses each number once.
I wrote a computer search for all ways to combine the 4 numbers around the circle with operations +, -, *, / in a way that it produces the value in the circle for the left and right case. The only formulas that came out are: (N + E + W - S) and (N + E + |W - S|), with many variations (permutations of the terms, various placement of brackets). These evaluate to respectively 16 and 6 for the middle case.
But these don't appear in the choices.
So either the formula is unusually complicated or there is a typo. I believe the second option is more likely.

It's:
9 (C). The formula is $|top-base|+|left-right|+k$, where $k=4,3,2$.
