which term of AP 121..117..113...... is its first negative term ?​

Answer 1

Heya Mate...........................

Here is your answer...............................

_________________________________________________________________________________

Tn = a + (n - 1)d

    = 121 + (n - 1)-4 = 0

    = 121/4 +1 = n

    = n = 31.25

So, 32th term is its first negative term.

Answer 2

hey here is your answer :----

➡a +( n-1)d < 0

➡121 + ( n -1)-4 < 0

➡121 -4n + 4 <

➡125 - 4n < 0

add 4n on both the sides the we get -

➡125 - 4n + 4n < 4n

-4n and 4n will get canceled

the we get -

➡125 < 4n

divide this eqh by 4

➡125/4< n

➡31.2< n

the value of n is 32 because n is greater than 31.2

hope it helps u....❤❤❤
