Question

Which term of the progression 19, 18 1/5 is the first negative term?

Answer 1

Answer:

Lets take..a+(n-1)d<0----------------1

●a=19

d=t2-t1

i.e, 91/5-19

so...we get -4/5.

thrfr...d=-4/5

so puttng in eqn...1

a+(n-1)d<0

19+(n-1)×-4/5<0

19+(-4n/5+4/5)<0

19-4n/5+4/5<0

95/5-4n/5+4/5<0

(95 - 4n + 4 ) /5<0

99 - 4n < 0

99 < 4n

99/4 < n

24 3/4 < n

mst near no. to 24 3/4 is 25..

so the frst negative term is 25.
