Find the first negative term of the sequence 999 995 991 987​

Answer 1

Answer: -1

Step-by-step explanation:

We have a=499

d= -4

We have to find n For Which a(n)<0

Therefore a+(n-1)d=0

• 999+[n-1](-4)=0

• -4n+4=-999

• -4n=-1003

n=1003/4

=250.75

All the terms starting from a(251) and above are negative terms.

a(251)=-1
