Question

Arithmetic progression formula when sum of numbers and product is given

Answer 1

TAKE THIS EXAMPLE:

Find the numbers in A.P. those sum is  24  and product is  440  

If the sum of three numbers in A.P. is 24 and their product is 440, find the numbers.

My Approach: Let the numbers be a,a+d,a+2d

So, according to question

3a+3d=24

a+d=8

and

a(a+d)(a+2d)=440

8a+ad=55

AND THEN PROCEED..
