let us take a+(n-1)d=0 then we will get n as 32.5 but n cant be decimal therefore the next natural number will be n.so n=33.by substituting n=33 in a+(n-1)d we will get-2

are u satisfied?

D: nyaah

not so much, a little confusing in the second part of getting -2.Can you explain it again?Pleaseee :P

Let first negative term be An
a=125,d=-4
An<0
,
a+(n-1)d<0,
125+(n-1)(-4)<0,
(n-1)(-4)<-125,
(n-1)4>125,
n-1>31.25,
n>32.25,
n=33,
33th term is first negative term
