MARK AS BRANLIEST PLEASE,
ITS NOTGTERM, IT'S 8TERM
let the AP : a, a+d, a+2d ......
to calculate the nth term of an AP from last, we need to write it in reverse order
New AP : 65, 65+d, 65+2d
Let the common difference be D
D= a2-a1
D= (65+d)-65
D= 65+d-65
D= d
Now,
the 8th term =30
a1+(8-1)D = 30
65+7d =30
7d=30-65
d= -35/7
d= -5
