Question

Find the three numbers in Arithmetic Progression whose sum is 15 and their
product is 80.​

Answer 1

4) Distinguish between Bathing soap and washing soda

Answer 2

Answer:

Let the terms be a-d, a+d and a

Thus, a+d+a-d+a = 15

3a = 15

a = 5

Also, a(a+d)(a-d) = 80

a(a^2-d^2) = 80

5(25-d^2) = 80

25-d^2 = 80/5 = 16

d^2 = 9

d = +/- 3

whether u use -3 or +3 as d, u will always get 2, 5 and 8

Thus no.s r 2, 5, 8
