ok somebody sent me this on youtube but I don't think is a workable series

Rimbus Jift

@ray salmon Quick IQ test... Solve: 4, 5, 14, 185, ...

so first the difference between the numbers is 1,9,171

so far just some ideas

The factors of 171 are

$9+5=14$

$9\cdot 19=171 $

anyway ?

i plugged into W|F but didn't return a series

so far just some ideas

The factors of 171 are

**1, 3, 9, 19, 57, 171**

$9^0 =1$ and $4+1=5$

$9^1 =9$ and $5+9=14$$9^0 =1$ and $4+1=5$

$9^1 =9$ and $5+9=14$

$9+5=14$

**$9+14=19$**$9\cdot 19=171 $
