Chapter 7: Q. 17 (page 631)

Consider the series
Fill in the blanks and select the correct word:
$I f \lim_{k 鈫� 鈭�} \frac{a_{k}}{b_{k}} = 鈭� and {鈭�}_{k = 1}^{鈭�}_____diverges t he n {鈭�}_{k = 1}^{鈭�}_____(converges / diverges) .$

Short Answer

Expert verified

$The first blank is filled with {鈭�}_{k = 1}^{鈭�} b_{k} and second with {鈭�}_{k = 1}^{鈭�} a_{k} .$

Step by step solution

Step 1. Given information

$\lim_{k 鈫� 鈭�} \frac{a_{k}}{b_{k}} = 鈭�$ .

Step 2. Limit comparison test

$The limit comparison test states that for and be two series with positive terms then If \lim_{k 鈫� 鈭�} \frac{a_{k}}{b_{k}} = L Where L is any positive real number then either both converges or diverges . If \lim_{k 鈫� 鈭�} \frac{a_{k}}{b_{k}} = 0 and {鈭�}_{k = 1}^{鈭�} b_{k} converges then {鈭�}_{k = 1}^{鈭�} a_{k} converges . If \lim_{k 鈫� 鈭�} \frac{a_{k}}{b_{k}} = 鈭� and {鈭�}_{k = 1}^{鈭�} b_{k} diverges then {鈭�}_{k = 1}^{鈭�} a_{k} diverges .$

Step 3. Result

$If \lim_{k 鈫� 鈭�} \frac{a_{k}}{b_{k}} = 鈭� and {鈭�}_{k = 1}^{鈭�} b_{k} diverges then {鈭�}_{k = 1}^{鈭�} a_{k} diverges . Therefore, the first blank is filled with {鈭�}_{k = 1}^{鈭�} b_{k} and second with {鈭�}_{k = 1}^{鈭�} a_{k} .$
