Question

Statement 1:In a G.P. if the $open parentheses m plus n close parentheses to the power of t h end exponent$ term be $p$ and $open parentheses m minus n close parentheses to the power of t h end exponent$ term be $q$ , then its $m to the power of t h end exponent$ term is $square root of p q end root$
Statement 2: $T subscript m plus n end subscript comma blank T subscript m end subscript comma blank T subscript m minus n end subscript$ are in G.P.

Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
Statement 1 is True, Statement 2 is False
Statement 1 is False, Statement 2 is True

The correct answer is: Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1

Statement 2 is true as it is a property of sequence in G.P.
Now $T subscript m minus n end subscript comma blank T subscript m end subscript$ and $T subscript m plus n end subscript$ are in G.P> $open parentheses because T subscript m end subscript blank f r o m blank T subscript m minus n end subscript blank a n d blank T subscript m plus n end subscript blank f r o m blank T blank a r e blank a t blank s a m e blank d i s t a n c e close parentheses$
$therefore T subscript m end subscript superscript 2 end superscript equals T subscript m minus n end subscript T subscript m plus n end subscript$
$rightwards double arrow T subscript m end subscript equals square root of p q end root$
