Question

Sum of three number in AP is -3 and product is 8 find number

Answer 1

Answer:

Numbers are 2,-1,-4 or -4,-1,2

Step-by-step explanation:

Let the numbers be (a-d), (a), and (a+d)

a => 1st term

d => Common difference

a - d + a + a + d

= 3a

3a = -3

thus a = -1

Now,

(-1 -d)(-1)(-1 + d)

= d^2 -1

= 8

d^2 = 8 + 1

d^2 = 9

Thus d = +-3

Therefore, numbers are 2,-1,-4 or -4,-1,2
