What is the next number in the following series:

tester [92]

to get from 15 to 12 you subtract 3

to get from 12 to 17 you add 5

to get from 17 to 14 you subtract 3

to get from 14 to 19 you add 5

so, based on this pattern you can assume that you can get the next number by subtracting 3 from 19. so that means you'd do 19-3 and you would get 16 as your answer.

your answer is C.16

Hope this helps :)

The different councils consisting of 5 freshmen and 7 sophomores are possible 9216.

We have given that,

A pool of possible candidates for a student council consists of 14 freshmen and 8 software.

We have to determine the how many different councils consisting of 5 freshmen and 7 sophomores are possible

<h3>What is the combination?</h3>

$_n C_r=\frac{n !}{r ! (n-r) !}_n C_r = number of combinations\\\n = total number of objects in the set\\\r = number of choosing objects from the set$

The total number of the council is

$_{10} C_5\times _9 C_7$

=252(36)

=9216

The different councils consisting of 5 freshmen and 7 sophomores are possible 9216.
