Find the missing number in the following series. 3, 8, 22, 63, 185,_____

Answer 1

List of numbers = 3 8 22 63 185 ?

Difference of numbers= 5 14 41 122 365

The trend seems to be

3x5-1 = 14

3x14-1 = 41

3x41-1 = 122

So, the next difference number should be 3x122-1 = 365

Therefore, ? - 365 = 185 or

The missing number (?) = 550
