Step-by-step explanation:
to know whether it is geometric progression or not, you need to find the common ratio. to find the ratio divide the (n+1)th term by n th term
so, 12/-4 = -3
also, -36/12 = -3
here u see the ratio is always same, i.e., common ratio.
thus u can say it is a geometric series with common ratio -3
MN is the mid-line of a trapezoid HJLK.<span>
The length of the mid-line of a trapezoid is half of the sum of the lengths of its bases </span>⇒
<span>
(KL + HJ)/2 = MN
(KL + 45)/2 = 28
KL + 45 = 28 * 2
KL + 45 = 56
KL = 56 - 45
KL = 11

There is an explanation in the photo below, as well as some things to remember!
Based on the given values above, we will be able to determine the expected number of viewers after four weeks by just multiplying the number of viewers to 18% per week. So the initial is 25 for this next. So for the first week, additional of 4.5 viewers. So the total would be 29.5 Second week, additional of 5.31, and the total would be 34.81. Third week, additional 6.27, the total would be 41.08. And on the fourth week, additional of 7.39, so the expected number of viewers would be 48.47. To round this off to the nearest whole number, we can get 48 viewers. Hope this helps.
