Answer 2

The First negative term in the AP is 8th term

Step-by-step explanation:

the given AP is 19,16, 13...

here

a = 19

d = a2-a1 = 16-19 = -3

now to find the fisrt negative term

$a_n <0$

$a_n = a+(n-1)d$

$a+(n-1)d <0\\19+(n-1)(-3) <0\\19-3n +3 <0\\22-3n<0\\-3n <-22\\n> \frac{22}{3} \\n>7.3$

therefore

the value of n must be greater than 7.3 i.e the 8th term

hence ,

the First negative term in the AP is 8th term
