Find an expression for the nth term (t_n) in each of the following

Serhud [2]

<h3><u>Answer:</u></h3>

$\boxed{\pink{\tt\longmapsto The \ nth \ term \ of \ the \ sequence\ is \ given \ by \frac{1}{n}}}$

<h3><u>Step-by-step explanation:</u></h3>

A sequence is given to us is , and we need to find expression for nth term of the sequence. The given sequence is ,

$\boxed{\boxed{\blue{\qquad\bf 1 , \dfrac{1}{2},\dfrac{1}{3},\dfrac{1}{4},\dfrac{1}{5},\dfrac{1}{6}}}}$

When we flip the numbers , we can clearly see that the number are in Harmonic Progression.

That is when we flip the numbers they are found to be in Arithmetic Progression .

And nth term of an Harmonic Progression is :-

$\boxed{\purple{\bf T_{(Harmonic \ Progression)} = \dfrac{1}{a+(n-1)d}}}$

Hence here

Common difference = 1
First term = 1 .

<u>Substituting the respective values,</u>

$\bf\implies T_{n}= \dfrac{1}{a+(n-1)d} \\\\\bf\implies T_{n} = \dfrac{1}{1+(n-1)1}\\\\\bf\implies T_n = \dfrac{1}{1+n-1}\\\\\bf\implies\boxed{\red{\bf T_{n}=\dfrac{1}{n}}}$

<h3><u>Hence the nth term of the given sequence is given by ¹/n .</u></h3>

Solve for x <br> 6x+3y=54<br> 2x+y=18

butalik [34]

Step-by-step explanation:

6x+3y=54

- 2x+y=18

I'm going to be using the elimination method cause it seems easiest here. so for the elimination method u choose a variable to eliminate I chose y u could do x too if u want to. so first step would be to multiply the second equation by 3. 6x+3y=54

so now u just have to eliminate

6x+3y=54

- 6x+3y=54

because these cancel out the answer would be an infinite solution
