Answer 1

Once again, we must find the pattern.

Answer 2

16, 48, 80 which is increasing

Answer 3

How is it increasing?
Is it being multiplied? Is it being added by a value?
Or both... :D

Answer 4

well i think it's going by 32 and just adding on from there

Answer 5

Yup! our sequence, therefore is

?? = 32(n) + n

Answer 6

Solve for ?? if n is 6
