6.	How many terms of the AP 65, 60, 55, ........... be taken so that their sum is zero ?
Answer» Answer 27 TERMS of the given AP are required so that their sum becomes 0 Given The AP is 65,60,55,........ To Find How many terms of the given AP to be taken so that their sum is 0 Solution Given , the AP 65 , 60 , 55 , ...…... Here , first term , a = 65 COMMON difference , d = -5 Let us consider sum upto ‘N’ terms be 0 Now we know that , $\sf \longrightarrow S_{n} = \dfrac{n}{2}\{ 2a + (n -1)d \} \\\\ \sf\implies 0 = \dfrac{n}{2} \{2\times 65 + (n - 1)(-5) \} \\\\ \sf\implies 0 = n\{ 130 - 5n + 5 \} \\\\ \sf\implies n\{135 - 5n \} = 0 \\\\ \sf\implies 5n -135= 0 \\\\ \sf\implies 5n = 135 \\\\ \sf\implies n = 27$ Thus 27 terms of the given AP must be taken so that their sum becomes 0

6.

How many terms of the AP 65, 60, 55, ........... be taken so that their sum is zero ?

Answer»

Answer

27 TERMS of the given AP are required so that their sum becomes 0

Given

The AP is 65,60,55,........

To Find

How many terms of the given AP to be taken so that their sum is 0

Solution

Given , the AP

65 , 60 , 55 , ...…...

Here ,

first term , a = 65

COMMON difference , d = -5

Let us consider sum upto ‘N’ terms be 0

Now we know that ,

$\sf \longrightarrow S_{n} = \dfrac{n}{2}\{ 2a + (n -1)d \} \\\\ \sf\implies 0 = \dfrac{n}{2} \{2\times 65 + (n - 1)(-5) \} \\\\ \sf\implies 0 = n\{ 130 - 5n + 5 \} \\\\ \sf\implies n\{135 - 5n \} = 0 \\\\ \sf\implies 5n -135= 0 \\\\ \sf\implies 5n = 135 \\\\ \sf\implies n = 27$

Thus 27 terms of the given AP must be taken so that their sum becomes 0

Answer»

X+Y+Z=20

2X+Y-Z=23

3X+Y+Z=46 ADD THE SECOND & THIRD EQUATIONS.

------------------

5X+2Y=69

ADD THE FIRST & SECOND EQUATIONS.

X+Y+Z=20

2X+Y-Z=23

-----------------

3X+2Y=43 NOW ADD THIS EQUATION TO THE PREVIOUS SUM TIMES -1.

-5X-2Y=-69

------------------

-2X=-26

X=-26/-2

X=13 ANS.

5*13+2Y=69

65+2Y=69

2Y=69-65

2Y=4

Y=4/2

Y=2 ANS.

13+2+Z=20

15+Z=20

Z=20-15

Z=5 ANS.

PROOF:

2*13+2-5=23

26-3=23

23=23
