Answer:
This problem is not considered as arithmetic sequence since we cannot determine the common difference.
I consider this problem as Fibonacci Sequence, adding the first two terms will generate the next term which is 8x.
Hence,
2x, 4x, 8x, 14x, 22x
If the problem like this:
2x, 4x, 6x, 8x
Solution:
To solve for the common difference, subtract the second term by the first term, we have
4x - 2x = 2x
so, 2x is our common difference or d.
