If a_1=5a 1

=5 and a_n=-2a_{n-1}a
n

=−2a
n−1

then find the value of a_4a
4

.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%

i believe it's a.

i'm not sure on this one, most likely correct.

good luck!
