Step-by-step explanation:
100% = X
50% = 100%/2 = X/2
X decreased by 50 means X - 50% = X - X/2 = X/2
now,
100% = X/2
50% = 100%/2 = X/2 / 2 = X/(2×2) = X/4
increasing the previous result by 50% means
X/2 + 50% = X/2 + X/4 = 2X/4 + X/4 = 3X/4
so, comparing this to the original X (= 4X/4), we are X/4 short.
I think it is A 54 because I did it already and I got a 100
The Answer Is Non Linear And Increasing .
Answer:
f(x+1) = -3/4 × f(x)
Step-by-step explanation:
first of all, the sign of the numbers in the sequence is alternating. so, there must be a "-" involved.
that eliminates the first and third answer options.
and the absolute values of the numbers in the sequence are going down. |f(x+1)| < |f(x)|
that eliminates the fourth answer option, as this says that
|f(x)| < |f(x+1)|. and that is the opposite of how the actual sequence behaves.
