The common difference dividing each term from the next is 18.
Then a(n) = -5 + (n-1)(18)
Check: find a(1) using this formula. Is a(1) = -5? a(1) = -5 + (1-1)(18) does equal -5.
Find a(2); a(2) = -5 + (2-1)(18) = -5 + 18 = 13. Correct.
Answer:
$5.80
Step-by-step explanation:
The 12 members spent $48 in total and the 8 nonmembers spent 68 in total. If you add those two together and divide by 20 you get 5.8.

X =10 use second equation
10²+3
100+3
103
last option is correct
Set up a proportion of acres to days. 1/2 acre is to 4 days as 2 3/4 acres is to x days.
x= # days to clear 2 3/4 acres
2 3/4 to improper fraction= 11/4
(1/2)/4 = (11/4)/x
cross multiply
(1/2 * x) = (4 * 11/4)
on the right, the 4 "cancels out"
1/2x= 11
divide both sides by 1/2
x= 11 ÷ 1/2
to divide fractions, multiply by reciprocal/inverse of 1/2
x= 11 * 2/1
x= 22 days
ANSWER: It would take 22 days to clear 2 3/4 acres.
Hope this helps! :)
