Question

which term of AP, 121 ,117, 113 is it's first negative term ​

Answer 1

difference between 2nd term and 3rd term is,

= (t3 - t2)

= (113 - 117)

= (-4)

so, d= (-4)

here series is in A.P

from this value we get that,

first negetive value will -> 0 + (-4) = -4

now, we have to calculate which term of this series is (-4)

here , l = (-4) , a1 = 121, d = (-4) , n = ?

we know,

I = a1 + (n-1)d

=> (-4) = 121 + (n-1)×(-4)

=> (n-1)×(-4) = -125

=> (n-1) = (125/4)

=> n = 31.25

here n>31.25

so, the term will 32.

ans= 32nd term of this ap series will first negetive term
