Question

$\frac{1}{3} \frac{1}{4} \frac{1}{6} \frac{1}{7} \: it \: is \: proportion \: or \: not$
​

Answer 1

Answer:

No

Step-by-step explanation:

Check if they are in A.P.

$\dfrac14 - \dfrac13 = -\dfrac{1}{12}$

$\dfrac16 - \dfrac14 = -\dfrac{1}{12}$

$\dfrac17 - \dfrac16 = -\dfrac{1}{42}$

They are not in A.P.

Check if they are in G.P.

$\dfrac14 \div \dfrac13 = \dfrac34$

$\dfrac16 \div \dfrac14 = \dfrac23$

They are not in G.P.

Check if they are in H.P.

$4 - 3 = 1$

$6-4=2$

They are not in H.P. either
