Ex 9.1 Q 14 , 15 and 16

Find the sum of series 4 - 9x + 16 x^(2) - 25 x^(3) + 36 x^(4) - 49 x^(5) + ...oo

The sum of infinite terms of the series 5 - 7/3 + (9)/(3 ^(2)) - (11)/( 3 ^(3))+……..o is

Number of common terms in both sequence 3, 7, 11,...., 407 and 2, 9, 16,....,905 is

Number of identical terms in the sequence 2, 5, 8, 11, ... up to 100 terms and 3, 5, 7, 9, 11, ... Up to 100 terms is

Check if the sequence is an AP 1,3,9,27,....

How many terms are there in the sequence 3,6,9, 12 ,....... 111 ?
