Given:
The sequence is 25, 20, 15, 10, 5.
To find:
The ninth term of the given sequence.
Solution:
We have,
25, 20, 15, 10, 5
It is an AP because the difference between two consecutive terms are same.
Here,
First term (a) = 25
Common difference (d) = 20-25
= -5
The nth terms of an AP is

Where, a is the first term and d is the common difference.
Putting a=25, n=9 and d=-5 to get the 9th term.




Therefore, the ninth term of the given sequence is -15.
Answer:
<h2>
19.99(x+3)+ 14.99(y+4)</h2>
Step-by-step explanation:
Step one:
given data
day one
x shirts that cost $19.99 each and
y pairs of shorts that cost $14.99 each.
Day two
3 more shirts that cost $19.99 each and
4 more pairs of shorts cost $14.99 each.
Step two:
the total number of shirts is
x+3
and the total number of shorts is
y+4
The total cost is ex[ressed as
19.99(x+3)+ 14.99(y+4)
