Answer:
n = 9
Step-by-step explanation:
20 + 18 + ... + 6 + 4
---------------------------
a = 20 ; d = -2 ; n = ?
--------
4 = 20 + (n-1)(-2)
-16 = (n-1)(-2)
---------
n-1 = 8
n = 9
-------
S(9) = (9/2)(20+4)
S(9) = 4.5*24
S(9) = 108
The problem ask to compute or find the value of x if AC=12, BC = X+1, DC = 2X and EC = 9, base on the said data, and in my further calculation about the problem, i came u p with a solution that leads to an answer of X=2. I hope you are satisfied with my answer
