40%
Because, 2/5 equals 4/10. 10x10=100, so 4x10=40, so 40%.
Since the price is going down, it's going to be a percent decrease. Now to find the percent, we divide the "after" price by the "before" price.
240 / 320 = 0.75 = 75%
The item had a 75% decrease.
The total value of the sequence is mathematically given as
498501
<h3>The sum of the sequence is..?</h3>
Generally, the equation for Gauss's Problem is mathematically given as
The sum of an arithmetic series;
1+2+3+...+n= n(n+1)/2
Given an arithmetic sequence,
1+2+3+...+998,
Here,
n = 998
1+2+3+...+n=n(n+1)/2
1+2+3+...+998=98(998 + 1)/2
998 x 999 1+2+3+...+998 =2
1+2+3+...+998 = 498501
In conclusion, 498501 is the total value of the sequence.
