Two sequences cannot be in both AP and GP together .

Which of the following sequences are A.P. ? If it is an A.P. , find next two terms. 2,-2,-6,-10,……….

Which of the following sequences are A.P. ? If it is an A.P. , find next two terms. 5,12,19,26,…….

Assertion : Restriction enzymes recongise palindromic sequences. Reason : Palindromic sequences read same in both directions of the two strand.

Which of the following sequences are A.P. ? If it is an A.P. , find next two terms. (3)/(2),(1)/(2),-(1)/(2),………..

Which of the following sequences are A.P. ? If it is an A.P. , find next two terms. 1,1,2,2,3,3,………

if a sequence of number is in GP show that their logarithms are in A.P

1,3,9 can be terms of (A) an A.P. out not of a G.P (B) G.P. but not of an A.P. (C) A.P. and G.P both (D) neither A.P nor G.P

Prove that three unequal numbers cannot be in GP when each number increased (or decreased) by the same quantity are in AP.
