    wait, that comes into use if the question says the numbers are consecutive but its almost useless if it doesnt say that

    Assume The Numbers To be a, a+d , a+2d and make out two equations by first adding them and then multiplying them ... Make their sum equal to 15and product equal to 45.... Then U will get two equations in terms of 'a' and 'd' Then Subtract Those both and U will get The values of 'a' and 'd' .... Then ultimately you will get what the numbers are!! ... Got it??
