Averaging formula:
A=sum of n values / n
Substitute the variables,
c is the average,
a and b are the test scores
∴

rearrange for b


Answer:
The next three terms of the sequence are 17, 21 and 25.
The 300th term of the sequence is 1197.
Step-by-step explanation:
The statement describes an arithmetic progression, which is defined by following formula:
(1)
Where:
- First element of the sequence.
- Progression rate.
- Index of the n-th element of the sequence.
- n-th element of the series.
If we know that
,
and
, then the progression rate is:


The set of elements of the series are described by
.
Lastly, if we know that
, then the 300th term of the sequence is:


And the next three terms of the sequence are:
n = 5


n = 6


n = 7


The next three terms of the sequence are 17, 21 and 25.
The 300th term of the sequence is 1197.
Well
n+2d+5q=100
n=3d
q=n
Therefore n=15 and q=15
Hope this helped :)
