Question
If $\mathrm{a}, \mathrm{b}, \mathrm{c}$ are in A. P, then $7^{\mathrm{a}}, 7^{\mathrm{b},}, 7^{\mathrm{c}}$ are in(a) HP(b) AP(c) AGP(d) GP
Step 1
Step 1: Given that a, b, c are in Arithmetic Progression (AP), we can write this as: \[b = \frac{a+c}{2}\] Show more…

If $\mathrm{a}, \mathrm{b}, \mathrm{c}$ are in $\mathrm{AP}$ and $\mathrm{a}, \mathrm{mb}, \mathrm{c}$ are in GP, then $\mathrm{a}, \mathrm{m}^{2} \mathrm{~b}, \mathrm{c}$ are in (a) AP (b) $\mathrm{GP}$ (c) HP (d) AGP
If $\mathrm{a}^{2}, \mathrm{~b}^{2}, \mathrm{c}^{2}$ are in $\mathrm{HP}$, then $\mathrm{a}^{2} \mathrm{~b}^{2}, \mathrm{a}^{2} \mathrm{c}^{2}, \mathrm{~b}^{2} \mathrm{c}^{2}$ are in (a) GP (b) AGP (c) $\mathrm{HP}$ (d) AP
If $\mathrm{a}, \mathrm{b}, \mathrm{c}$ are in $\mathrm{AP}$, then $\mathrm{b}+\mathrm{c}, \mathrm{c}+\mathrm{a}, \mathrm{a}+\mathrm{b}$ are in (a) AP (b) HP (c) GP (d) AGP
