ReplyDeleteif there r no other caonditions

Delete1,2,1

1,3,1

1,5,1

1,7,1 etc..can be considered as ur answer

let's consider three number p, q, r

ReplyDeleteby condition, q - p = r - q → q = (p + r) / 2.

It means that the 2nd number is in between 1st and 3rd number.

So the number would be 1 * (3/2) * 2 = 3

This one works too.

Delete-1,1,3

ReplyDeleteProduct of those would be negative and Negative numbers are not Prime!

Delete-3, -1, 1

ReplyDelete3 - 1 = 2 but 1 - 3 = -2

Deletethey are no same!

It is -3, -1, and 1

ReplyDelete-3 x -1 x 1 = 3

-1 - (-3) = -1 + 3 = 2

1 - (-1) = 1 + 1 = 2
