Question

45.What is the first negative term of the A.P. -17,-14,-11,.......​

Answer 1

Answer:

I think the question should be what is the 1st positive term of this ap. if so then

a=-17

d=+3

nth term>0

=a + (n-1)d >0

=-17 + (n-1)3 >0

=3n-3>17

=3n>20

=n>6.66

therefore n=7

so the first term which is positive is 7th term.

t7 =a +6d

=-17 +6×3

=1
