Question

Find the missing number? Explain your answer-
992,552,.......,132,30,6
​

Answer 1

6=2*3

30=5*2*3

132=11*2*2*3

Here if we observe carefully 2*3 is being multiplied by alternative primes i.e prime sequence 2,3,5,7,11,13,17 not only that in third number i.e 132 it is also multiplied by 2 next is 306 because306=17*3*3*2 here we multiply with 3 next we multiply with two twice i.e 552=23*3*2*2*2
