If you see the numbers in and around the first pentagon you will notice the following;
(17 + 4) – (6 + 9 + 2) = 21 – 17 = 4 = number in the centre of the pentagon.
Similarly, this holds good in the second pentagon;
(19 + 1) – (6 + 7 + 2) = 20 – 15 = 5
Therefore to find the missin gnumber;
(17 + 9) – (8 + 6 + 8) = 26 – 22 = 4
Answer = 4.
