Answer 1

Answer:

Hence, the 19th term of the given AP is 0.

Answer 2

19th term

Step-by-step explanation:

Given,

A.P : 72, 68, 64, 60

a = 72

d = 68 - 72 = - 4

l = 0

To find : n = ?

n = [ ( l - a ) / d ] + 1

= [ ( 0 - 72 ) / - 4 ] + 1

= [ - 72 / - 4 ] + 1

= [ 72 / 4 ] + 1

= 18 + 1

n = 19

19 th term of an A.P is 0.
