There may be more than one solution, but if we take the difference between the numbers of the sequence, we get
3-1, 11-3, 43-11
=2,8,32
which are powers of 2
=2^1, 2^3,2^5
If we believe the next difference is 2^7=128, then the next in the sequence will be 43+128=171

Murrr4er [49]

Answer: $\left \{ {{l=3t+6} \atop {l+t=110}} \right.$

Step-by-step explanation:

Let be "l" the number of CDs Ms.Kitts sold last week, and "t" the number of CDs she sold this week.

You need to remember that:

1. The word "times" indicates a multiplication.

2. The word "more" indicates addition.

Then, the sentence "Last week she sold 6 more than 3 times the number of CDs that she sold this week" can be represented with equation:

$l=3t+6$

According to the information given in the exercise, the sum of the number of CDs Ms. Kitts sold last week and this week is: 110 CDs.

Since a sum is the result an Addition, you can write the following equation:

$l+t=110$

Therefore, the System of equations that can be used to find the number of CDs she sold last week and the number of CDs she sold this week, is:

$\left \{ {{l=3t+6} \atop {l+t=110}} \right.$
