Step-by-step explanation:
104,96,88,80........
given
a=104
d = a2-a1
= 96 -104
= -8
first negetive term be -8
because in this A.p the difference between us is -8 and we will see that it is like a table of 8 . in opposite directions.
an= a+(n-1)d
-8 = 104 +(n-1)-8
-8 -104 = (n-1) -8
-112/-8 = n-1
14 = n-1
14+1 = n
n= 15
