Answer:
78,792,000,000,000 miles
Step-by-step explanation:
(5.88 * 10^12) * 13.4 = 78,792,000,000,000
Step-by-step explanation:
The fraction is 4/10 * 2/9 = 4/45.
To find if a series is either geometric or arithmetic:
it must satisfy this property:
Arithmetic:
a(n+1) - a(n) = const
Geometric:
a(n+1)/a(n) = const
In your case:
r1 = 7 -4 = 3
r2 = 12 - 7 = 5
r1 != r2 (not arirthmetic)
Geometric check:
r1 = 7/4
r2 = 12/7
r1 != r2 (not Geometric)
so neither.
