Question

fill up the boxes
____, -5, ___ ,____ ,____ , 7
(Hint :- this is question of arithmetic Progression)
​

Answer 1

Answer:

Step-by-step explanation:

The second term is given ,

A2= -5

And A+d=A2= -5

A+d= -5(1st equation)

The sixth term is ,

A6= 7= A+5d

A+5d=7(2nd equation)

From 1st and 3nd ,

A+d= -5

A+5d=7

On solving by eliminating method,

A= -8

d=3

First term = -8

Second term -5

Third term = A+ 2d

= -8+ 2×3

= -2

Fourth term = A+3d

= -8+3×3

=1

Fifth term = A+4d

= -8 + 4×3

= 4

I hope u understand !

Answer 2

Answer:

Given that

a2= a+d= -5. & a6=a+5d=7

SO BY ELIMINATION METHOD I AM ELIMINATING

a+5d=7

a+ d = - 5

After eliminating this term we get

d= 3................(i)

putting (i) in a2= a+d = -5

a+3= -5

a= -8 .............(ii)

a3 = -2

a4 = 1

a5 = 4
