Question

guys pls tell me how to find the first negative term in an AP... pls make it soon it's a humble request...​

Answer 1

Answer:

Step-by-step explanation:

Here series is 114,109,104.......

Common differnce(d)109 - 114 = 104 - 109 = - 5.

                Therefore given sequence is an A.P.

                First term (a) = 114

                Common difference (d) = - 5

                For finding first negative term

                Tn < 0

                a + (n - 1)d < 0

                114 + (n - 1)(- 5) < 0

              114 - 5n + 5 < 0

          119 - 5n < 0

           or   - 5n < - 119

           or   5n > 119

           or   n > 119/5

                 n > 23.8

                 Therefore first negative term is 24
