Two sequences cannot be in both A.P. and G.P. together.
False
Every progression is a sequence but the converse, i.e., every sequence is also a progression need not necessarily be true.
True
Any term of an A.P. (except first) is equal to half the sum of the terms which are equidistant from it.
True
The sum or difference of two G.P.s is again a G.P.
False
If the sum of \(n\) terms of a sequence is a quadratic expression then it always represents an A.P.
False
