# Can you find the missing number?

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:

+0, *2, +4, *6, +8, *10

third:

968

because:

sum of the digits squared and multiplied by 2

The first sequence

So the next term is

92
