Answer:
2+3n
Step-by-step explanation:
This question is based on a topic called sequence and series,under which we have the arithmetic progression
The formula for arithmetic progression is a+(n-1)d
In which a is the first number,n is the nth term and d is the difference
Back to the question
a=5,n=it's not given,d=3
Using the general formula
a+(n-1)d
5+(n-1)3
Open the bracket first
5+3n-3
Collect like terms
5-3+3n
2+3n
The answer is 2+3n
And it can be solved further only if we are given the value of n...the question even stated that we should solve in terms of n
Therefore the answer is 2+3n
Answer: 36%
Step-by-step explanation:
Since the price last week, was 4 boxes for $5. Therefore, the price per box will be:
= $5/4
= $1.25 per box
This week they mark a new price at 5 boxes for $4. The price per box will be:
= $4/5
= $0.8 per box
The percent decrease in the price per box this week will be:
= (1.25 - 0.80)/1.25 × 100
= 0.45/1.25 × 100
= 36%
The Percentage decrease is 36%
