PLEASE HELP!! Which sequence is generated by the function f(n + 1) = f(n) – 2 for f(1) = 10?

–10, –12, –14, –16, –18, ...
–2, 8, 18, 28, 38, ...
8, 18, 28, 38, 48, ...
10, 8, 6, 4, 2, ...

step-by-step explanation:

if x = 2 you have to find x to finish the problem

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
