Question

The sum of the three consecutive numbers is 15 and product is 80 find the numbers

Answer 1

Answer:

The numbers are 2, 5, 8

Step-by-step explanation:

Let the first term be a and common difference be d.

The three terms are,

a−d,a,a+d

As, the sum of three terms is 15, then,

a−d+a+a+d=15

3a=15

a=5

As, the product of three terms is 80, then,

(5−d)5(5+d)=80

5(25−d2)=80

25−d2=16

d2=9

d=±3

The numbers are 2,5,8 or 8,5,2.
