Answer 1

Answer:

$\large\green{\sf{⚡Apporpiate Question ⚡}}$

Dear student ,

Solution:

Step-by-step explanation:

ACO 1 The series that we have is: 1² =1

Apply p-test:

If the series is of the form

100 1 Σ, where p > 0 n=1 n²

If p > 1,

then the p - series converges

=> p = 2, p > 1

Thus the series is converging in nature.

Hope You get it !

$\bold{Let \: the \: number \: be \: x}$

$\bf{According \: to \: the \: question}$

$\bold{\frac{2}{3}x \: = \frac{1}{3}x + 3 }$

$\bold{ \frac{2}{3} x - \frac{1}{3}x = 3 }$

$\bold{ \frac{2x - x}{3} = 3}$

$\bold \green{x = 9}$
