Initial number of students: 220
Final number of students : 180
Multiply the initial number of students (220) by the percentage change in decimal form (divided by 100) - That expression must be equal to 180.
220 x = 180
Solve for x:
x=180/220
x= 0.818181
multiply by 100
81,81 %
100%-81,81% = 18.18%
Percent change: 18.18%

Answer:
Common difference of the sequence is -7.
Step-by-step explanation:
Given:
First term a = 5
Tenth term
= -58
we need to find the common difference d.
Now let the number of terms will be 10 since tenth term is given;
Hence n =10
Now Using Arithmetic Progression formula we get;

Now Substituting the given values in the formula we get;

Hence Common difference of the sequence will be -7.
