Question

What is the explicit rule for the sequence?

34,26,18,10, …


an = 26 − 8n

an = 42 − 8n

an = 34n − 26

an = 34n + 42

Answer 1

OPTION B

Explanation:

Answer 2

the sequence given is an arithmetic sequence;
the explicit formula for the sequence is:
an=a+(n-1)d
where
a=first term
n=index
d=common difference
from the sequence
a=34
d=26-34=-8
thus the explicit formula will be:
an=34-8(n-1)
an=34-8n+8
an=42-8n
