Answer:
yes to both
Step-by-step explanation:
If the sequences are arithmetic then the common difference d, between adjacent terms will be equal.
35, 32, 29, 26, ...
d = 32 - 35 = 29 - 32 = 26 - 29 = - 3
Hence sequence is arithmetic
- 30, - 40, - 50, - 60, ....
d = - 40 - (- 30) = - 40 + 30 = - 10
d = - 50 - (- 40) = - 50 + 40 = - 10
d = - 60 - (- 50) = - 60 + 50 = - 10
Hence sequence is arithmetic
