135

Consider a group of 3 numbers, (4, 5, 9), (12, 15, 27), (36, 45, 81), (108, x, y)
2nd number of each group is incremented by 3⁰, 3¹, 3², .... sequentially.
3rd number is a sum of first two numbers.
Therefore, next number x = 108 + 3³ = 135

Take first 3 terms
4, 5 and 9 and these numbers are multiplied with 3 we got
4*3=12
5*3=15
9*3=27
if you observe that the three numbers 12, 15 and 27 we got are the next three numbers in the given series so in the same way
45*3=135
We got the answer.
