Area of rectangular
A = W * X
X = 2W
W = X/2
A = W *X
A = (X/2) *X
A = X^2/2
It's the first one. Note that for each unit increase in x, y increases by 1/2:
outputs are 1/2, 2/2, 3/2, 4/2, corresponding to 1, 2, 3 and 4 as inputs.
Answer:
Step-by-step explanation:
> 2f%283-1%29+%2B+3%2A3-> 2f%282%29+%2B+9-> 2%282%29+%2B9->4%2B9=13
a%5B3%5D=+13...third term
n=4
-> 2f%284-1%29+%2B+3%2A4-> 2f%283%29+%2B+12-> 2%2813%29+%2B12->26%2B12=38
a%5B4%5D=+38.....forth term
