Here's 3 number puzzles/series. I'll give hints tomorrow if noone is able to solve them

11, 31, 71, 91, 32, ?

1, 1, 2, 6, 36, 44, ?

IF, 132 = 72 208= 200 390=288

 then what does, 
 8932= ?

second:

440

because:

third:

968

because:

sum of the digits squared and multiplied by 2

The first sequence

Reversed is 11, 13, 17, 19, 23... which are prime numbers

So the next term is

92
