The two numbers are -1 and -2
start with 0,1 add together =1 add to sequence, gives 0,1,1 add last two numbers =2 add to sequence, gives 0,1,1,2 add last two numbers =3 add to sequence, gives 0,1,1,2,3 add last two numbers = 5 add to sequence, gives 0,1,1,2,3,5 repeat forever, list is endless
multiplied to seventy and add to nine is impossible, but add up to 9 and multiplied to -70, or add up to -9 and multiplied to 70 are possible. In that case, 14 and -5 would do it (or -14 and 5)
