We do so to follow the rule of divisibility of each term(numbers).
<h2 /><h3><u>The Rule of Divisibility:</u></h3>
The rule of divisibility of numbers is a method applied in mathematics used to determine if a number or set of numbers is divisible by a particular integer without any remainder.
Let assume that we have a series of numbers;
From the rule of divisibility, since all the numbers are multiples of 2;
We can deduce that 2 can be the factor that is pulled out from the series to divide each term in the sum.

Answer:
Each CD cost 12.90 before tax
Step-by-step explanation:
41.10-2.40=38.7
38.7/3=12.90
Answer:
61.93
Step-by-step explanation:
use cosine x= 8/17
The sequence above is geometric progression.
The nth term of such sequence is given by;
Tn = ar∧(n-1),
Where a⇒first term and
r⇒common ratio
So, 1st term = 5×1.25∧(1-1) = 5×1.25∧0 =5
2nd term = 5×1.25∧(2-1) = 5×1.25 = 6.25
3rd term = 5×1.25∧(3-1) = 5×1.25² = 7.8125
4th term = 5×1.25∧(4-1) =5×1.25³ = 9.765625
5th term = 5×1.25∧(5-1) = 5×1.25∧4 = 12.20703125
6th term = 5×1.25∧(6-1) = 5×1.25∧5 = 15.25878909
90% x 18 = 16.2
Therefore, you answered about 16 questions correctly out of 18.
