Hello :
the common ratio is r = -95-(-100)=5
the general terme is : un= u1+(n-1)r
un = -100 +(n-1)(5)
un =-100 +5n-5
un = 5n-105
The last term is : 100
un =100
5n-105 = 100
5n =205
n = 41 (Number of terms)
The last term is : u 41
<span>the sum is : S= (41/2)(-100+100)=0</span>
Answer:
About 53% percent of the students went to the cafeteria.
Step-by-step explanation:

For this case, the first thing we must do is define variables.
We have then:
x: initial amount of cards
We now write the equation that models the problem:
Therefore, the initial amount of cards is 300
