Answer:

hello your answer is

Step-by-step explanation:

12 th term = a + 11d          

its is foundy by,

formula for AP is ( a + ( n-1 ) d )

for 12 term n = 12

so ( a + ( 12-1 ) d )

a + 11d  

Similarly, 8 th term = a + 7d

According to question:

a + 11d - a -7d = 24

4d = 24

d = 6

Hence common difference of AP is 6.
