Question

If sum of three term is -3 and product is 8 find the three term...???

Answer 1

Answer:

the product of first and the third term ...

The sum of three terms of an AP is 21 and the product of first and the third term ... term by 6 find the the three terms - Math - Arithmetic Progressions. ...

Answer 2

For AP:-

Three term is a-d,a ,a+d

now

a+d+a+a-d=-3

3a=-3

a=-1

Now

(a-d)×(a+d)×a=8

(a^2-b^2)×a=8

(-1)^2×b^2×(-1)=8

b=

$2 \sqrt{2}$

For GP:-

Three terms are

a, ar, a/r

a+ar+a/r=-3

a(1+r+r^2/r)=-3

(1+r+r^2)/r=-3..eq 1

And their product

a×ar×a/r=8.

a^3=8

a=

$2 \sqrt{2}$

put the value of a in eq 1
