Answer 2

Answer:

Step-by-step explanation:

ap = 115 , 110 , 105,.............

here, a = 116 and d = 110-115 = -5

let the nth term of the given ap be the first negative term.

Then , Tn<0 => a + ( n - 1 ) × d <0

=> 115+(n-1)×-5 <0

=> 115-5n+5 <0

=> 120-5n<0 => 120 <5n

=> 5n > 120 => n = 24

Therefore,

n = 24.

Hence, the 25th term is the first negative term of the given ap.
