What is the nth term rule of the quadratic sequence below? 7, 14, 23, 34, 47, 62, 79

Julli [10]

Answer:

Tn = Tn-1 + 2(n-1) + 5

Kindly note that Tn-1 means T subscript n-1

Step-by-step explanation:

Here, we want an expression for the nth term.

First term is 7

Then first common difference is 7

second common difference is 7 + 2

Third common difference is 9 + 2

So within the common differences, the nth term is 7 + (n-1) 2

Now, the nth term of the series would be;

Tn = Tn-1 + 7 + 2(n-1)

Tn = Tn-1 + 7 + 2n -2

Tn = Tn-1 + 2n + 5

Now there is a fix to this,

n for the term is not the same n for the common difference.

the 7th term works with the 6th common. difference, while the 8th term work for the 7th common difference.

So we might need to rewrite the final expression as follows;

Tn = Tn-1 + 2(n-1) + 5

If SP is equal to rupees 400 and loss percent is 20% find CP

Sindrei [870]

SP=400
Percentage of loss=20%

100-20=80%=400

$\\ \rm\longmapsto 80\%\:of\:CP=400$

$\\ \rm\longmapsto CP=400\times \dfrac{100}{80}$

$\\ \rm\longmapsto CP=5(100)$

$\\ \rm\longmapsto CP=500$
