Answer:
n=39/7 is not a natural nuber
thus no nth term are equal
Step-by-step explanation:
24, 20 , 16 , 12
a=24 ,d=20-24=-4
so nth term=24 +(n-1)(-4)
=24-4n+4
An1=28-4n
Now for -8,-5,-2,............
a=-8 d=-5+8=3
An2= -8 +(n-1)(3)
An2=-8+3n-3=3n-11
An1=An2
28-4n=3n-11
7n=39
n=39/7 is not a natural nuber
thus no nth term are equal
