" The maximum sum of the series "20+19(1)/(3)+18(2)/(3)+..." is "

The maximum sum of the series 20 +19(1)/(3)+18 (2)/(3) + cdots is

The minimum sum of the series : 20 + 19(1)/(3)+ 18(2)/( 3) +"..." is :

How many terms of the series 20+19(1)/(3)+18(2)/(3)+"...." must be taken to make 300? Explain the double answer.

Find the number of terms in the series 20,19(1)/(3),18(2)/(3)... the sum of which is 300. Explain the answer.

If the sum of the series 20 + 19 (3)/(5) + 19 (1)/(5) + 18 (4)/(5) + ….. upto nth tems is 488 and the nth terms is negative then :

The sum of the series (1)/(19!)+(1)/(3!17!) +(1)/(5!15) + ......... to 10 terms is equal to

The sum of the series 1^(3) + 2 ^(3) + 3^(3) + ...+15^(3) is

Find the number of terms in the series 20 ,19 1/3,18 2/3... the sum of which is 300. Explain the answer.
