Question
If the first and the $(2 n-1)$ th terms of an A.P., G.P. andH.P. are equal and their $n$th terms are $a, b, c$ respectively, then(A) $a=b=c$(B) $a \geq b \geq c$(C) $a+c=b$(D) $a c-b^{2}=0$
Step 1
P., G.P., and H.P. are equal. This implies that the $n$th term of each sequence is the arithmetic mean (A), geometric mean (G), and harmonic mean (H) respectively. Show more…

An A.P., a G.P and a H.P. have $a$ and $b$ for their first two terms. Show that their $(n+2)$ th terms will be in G.P. if $\frac{b^{2 n+2}-a^{2 n+2}}{a b\left(b^{2 n}-a^{2 n}\right)}=\frac{n+1}{n}$.
Given sum of the first $n$ terms of an A.P. is $2 n+3 n^{2}$. Another A.P. is formed with the same first term and double of the common difference, the sum of $n$ terms of the new A.P. is : (a) $n+4 n^{2}$ (b) $6 n^{2}-n$ (c) $n^{2}+4 n$ (d) $3 n+2 n^{2}$
In a sequence of $4 n+1$ terms, the first $2 n+1$ terms are in A.P. having common difference 2 and the last $2 n+1$ terms are in G.P. having common ratio $\frac{1}{2}$, If the middle term of the A.P. is equal to the middle term of the G.P. then the middle term of the sequence is (A) $\frac{n \cdot 2^{n+1}}{2^{n}+1}$ (B) $\frac{n \cdot 2^{n+1}}{2^{n}-1}$ (C) $\frac{n \cdot 2^{n}}{2^{n}-1}$ (D) None of these
