The plane has intercepts at (1, 0, 0), (0, 2, 0), and (0, 0, 6), so we can parameterize the surface 
by
where
and 
. Now
so the surface integral reduces to
where
so the surface integral reduces to
Answer:
(c) an = 4·(1/3)^(n-1)
Step-by-step explanation:
The explicit rule for a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
The factor in the recursive rule tells you the common ratio is 1/3, so the explicit rule is ...
an = 4·(1/3)^(n-1) . . . . . . matches choice C
