Answer:

D. aₙ= 2*3ⁿ⁻¹

Step-by-step explanation:

It is GP with common ratio of 3 as 6/2=18/6=54/18=162/54= 3 and the first term of 2

then aₙ= 2*3ⁿ⁻¹ is the formula

Answer:

$R = \frac {3ST}{2S + T}$

Step-by-step explanation:

Given the equation;

$\frac {3}{R} - \frac {1}{S} = \frac {2}{T}$

Rearranging the equation, we have;

$\frac {3}{R} = \frac {2}{T} + \frac {1}{S}$

Lowest common multiple (LCM) of S and T is ST.

$\frac {3}{R} = \frac {2S + T}{ST}$

Cross-multiplying, we have;

$3ST = R(2S + T)$

Making R, the subject of formula;

$R = \frac {3ST}{2S + T}$
