If the mth term of an A.P. be 1//n and nth term be 1//m then show that its ( m n )th term is 1.

Find the 30th term of the sequence: 1/2 , 1, 3/2 ,….

Find the 9th term of the G. P. 2, 1, (1)/(2) ,….

The first term of a sequence is (1)/(2) and the second term is (1)/(4) . Each term thereafter is the sum of the all the terms before it , If the n^(th) term is the first term of the sequence that is an integer , what is the value of n ?

The first term of a sequence is 1, the second is 2 and every term is the sum of the two preceding terms.The n^(th) term is.

Find the G.P. whose 2nd term is 12 and 6th term is 27 times the 3rd term.
