Answer:
Step-by-step explanation:
Second question
The second one is arithmetic. Each term has 11 added to it to get from one term to the next one. The key word is added. That makes it arithmetic.
a1 = 11
d = 11
an = a1 + (n - 1)*11
Example
n = 3
a3 = 11 + (3 -1)*11
a3 = 11 + 2*11
a3 = 11 + 22
a3 = 33 which it does.
First question
I see no way of getting either arithmetic or geometric. I agree with your answer.
