Ok, here's one

1,  3,  5,  11,  21,  43

85, 171, 341, 683

 

I like the following sequence:  6, 28, 496 (minor hint, the fourth term is a four-digit number and the fifth term is an eight-digit number)

Is this the sequence of numbers whose divisors add up to themselves? Perfect number or something they are called?

Yes, the 6, 28, 496, 8128 sequence are perfect numbers.
