I believe it is A and D. All you have to do is add them all together and if both sides are the same then its a correct answer.

Find the 4th term if the sequend in which a1 = 2 and a n+1 = -4a n + 2

pshichka [43]

$a_n_+_1=-4a_n_+_2$

dividing both sides by -4, we get:

$a_n_+_2=- \frac{a_n_+_1}{4}$

this means, each term is its previous term divided by -4.

now we can construct the sequence as follows:

$a_1=2$

$a_2=- \frac{a_1}{4}= - \frac{2}{4}= -\frac{1}{2}$

$a_3=- \frac{a_2}{4} =- \frac{ \frac{1}{2} }{4}=- \frac{1}{8}$

$a_4=- \frac{a_3}{4}=- \frac{ \frac{1}{8} }{4}=- \frac{1}{32}$

Answer: the last term is -1/32

A tank with capacity T gallons is empty. If water flows into the tank from pipe X at the rate of X gallons per minute, and water

Andrej [43]

A tank with capacity T gallons is empty. Tank will be filled in $\frac{t}{(x - y)}$ minutes

<u>Solution:</u>

Given, A tank with capacity T gallons is empty.

We have to find how many minutes will tank be filled?

Now, Water flows into the tank from pipe X at the rate of X gallons per minute,

And water is pumped out by pipe Y at the rate Y gallons per minute,

Then, together in one minute the amount of water filled will be x – y gallons [as X is greater than Y]

Now, the time take to fill tank = $=\frac{\text { capacity of tank }}{\text { amount of water filled per minute }}=\frac{t}{x-y}$

Hence tank will be filled in $\frac{t}{(x - y)}$ minutes
