The answer is 36 & 18 because i took the mean and figured out the what the difference had to be for it to equal 18 and used the same number to get to 54
J = 106% . x
S = 106% . (550+x)
O = 106% . 2x
S = 2(212+O) = 106%(550+x)
S = 424 + 2O = 583 + 106%x
2(106%.2x) - 106%x = 583-424
159 = 106%x( 4 - 1 )
159 = 106%x ( 3 )
159 = 318%x
1 = 318%x : 159
1 = 2%x
1 = 2/100 . x
x = 50

Answer:
an = -18 +11(n -1)
Step-by-step explanation:
We notice that the first term (a1) is -18, and the common difference (d) is -7-(-18) = 11. Filling these values into the form for the explicit formula gives ...
an = a1 +d(n -1)
an = -18 +11(n -1)
The formula for that represent the area covered by a marsh A(n) is .
An exponential decay is given by the function:
y = abˣ
Where a is the initial value of y, b is a constant which is less than 1, y, x are variables.
Since the area covered by a marsh, A, starts at 11500 acres, hence a = 11500. Since the area drops by 1/4 each year for n years, hence:
Therefore the formula for A(n) is

➷ Multiply 40 by 70 ( a cheat way is to do 7 x 8 and then add 2 zeroes on the end)
40 x 70 = 2800
Then do 40 x 2 ( do 4 x 2 and then add a zero)
40 x 2 = 80
Add these two values together:
2800 + 80 = 2880
