Question

Determine whether each sequence is arithmetic PLEEAASE!!!

Answer 1

or geometric.

Answer 2

1. 14, 19, 24, 29, . . .
geometric, 34, 39, 44
arithmetic, 32, 36, 41
arithmetic, 34, 39, 44
The sequence is neither geometric nor arithmetic.
2. –4, 8, –16, 32, . . .
arithmetic, 64, 128, 256
geometric, –64, 128, –256
geometric, –48, 64, –80
The sequence is neither geometric nor arithmetic.
3. 81, 27, 9, 3, . . .
arithmetic, 0, –3, –6
geometric, 0, –3, –6
geometric, 1, ,
The sequence is neither geometric nor arithmetic.
Find the next three terms in the sequence.
4. 3, 12, 21, 30, ....
40, 50, 60
38, 46, 54
39, 48, 57
36, 32, 39
5. 30, 22, 14, 6, ....
3, –12, –21
–1, –8, –15
–1, –2, 3
–2, –10, –18

Answer 3

arithmetic means that you add the pattern always has the same amount added to a term to get the next term....

e.g. 1, 4, 7, 10, 13, ....add 3

geometric means you multiply by the same amount

1, 2, 4, 8, 16,...... times 2
