Answer:
14:15
Step-by-step explanation: By reading the sentence carefully you should be able to get the first number and the second number. The sentence should tell you how to set it up.
7.76, when rounded, is 7.8
f(1) = 160
f(2) is -2 times the previous value
f(2) = -2 *f(1) = -2 * 160 = -320
f(3) = -2 * f(2) = -2 *(-320) = 640
f(4) = -2 * f(3) = -2 * 640 = -1280
f(4) = -1280
