Class 11 - Mathematics - Chapter 9: SEQUENCE AND SERIES

True or False

Two sequences cannot be in both A.P. and G.P. together.

Every progression is a sequence but the converse, i.e., every sequence is also a progression need not necessarily be true.

Any term of an A.P. (except first) is equal to half the sum of the terms which are equidistant from it.

The sum or difference of two G.P.s is again a G.P.

If the sum of \(n\) terms of a sequence is a quadratic expression then it always represents an A.P.
