There are several versions, but this one works well enough.
f(x)=2x
(y equals two to the x power.)
512 / 2 = 256 256 / 2 = 128 128 / 2 = 64 64 / 2 = 32 32 / 2 = 16 16 / 2 = 8 8 / 2 = 4 4 / 2 = 2 2 / 2 = 1
The nth term in the sequence means an unspecified number an unspecified distance along the series. 8 16 32 64 128... n. It is also a shothand notation so the reader knows that the sequence continues.

24. It should be 32 which is double of 16

This sequence is called the doubling sequence.
24. It should be 32 which is double of 16
Well, you see, in this set of numbers it is very easy to tell that each number gets doubled
128. 1+1=2 2+2=4 4+4= 16 16+16= 32 32+32= 64 64+64 = 128 128+128 = 256 256+256 =512 512+512= 1024 Each time take the answer from the previous problem and double it to find the next number in the sequence.
The sequence follows a pattern where each term is half of the previous term. Therefore, the next terms after 32 would be 16, 8, and 4.
Not sure what a gemetric sequence might be. 2 8 32 128 is the start of the geometric sequence defined by Un = 22n-1 for n = 1, 2, 3, ...
-4 +8 -16 +32 -64 +128 Next number in this sequence is 184
1, 2, 4, 8, 16, 32, 64, 128, -1, -2, -4, -8, -16, -32, -64, -128
