(4, -20, 100, 500, ...}

{1, 2, 3, 4, ...}

{-18, 11, 4, 3, ...}

{-3, -27, 243, -2187, ...}

{1, 8, 27, 64, ...}

{-9, -33, -57, -81, ...}

Answer 1

Explanation:

1) geometric

2) arithmetic

3) neither

4) geometric

5) neither

6) arithmetic

you can this by usin their formulas or

you see if it has common difference which is for arithmetic sequence or you find the common ratio which is geometric sequence.
