Answer:
= 6n - 3
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 9 - 3 = 15 - 9 = 21 - 15 = 6
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 3 and d = 6, then
= 3 + 6(n - 1) = 3 + 6n - 6 = 6n - 3
Smallest:x-2
middle:x
biggest:x+2
smallest+middle=biggest=(x-2)+(x)+(x+2)=3x
3x=192->3x/3=192/3->x=64
smallest: 64-2=62
There are 30 days in April 2018. 3,842,000 barrels divided by 30 days = 128066.66 barrels per day.
