Question

please answer this question ​

Answer 1

Step-by-step explanation:

Here a=20 and d=19 1/3 -20= -2/3

Let n terms form 300 as the sum

Applying formula

Sn=n/2(2a +(n-1)d)=300

=n/2(40 +(n-1)-2/3) =300

=122n-2n^2=1800

Applying quadratic formula we get ,

n =36 or 25

REASON FOR DOUBLE ANSWER

The terms from 26 to 36 are all 0
