Let's call the two integer numbers x and y. We know that xy = -26 and x + y = -11. By trying different combinations, we find that the numbers -13 and 2 satisfy both conditions, as -13 multiplied by 2 equals -26 and -13 plus 2 equals -11. So, the integer pair is (-13, 2).
26
24 + 2 = 26
2+11+13
There are no such consecutive integer as is so simple to prove! Suppose the first integer is x. Then the next (consecutive) integer is x+1. Then 2*x + 4*(x+1) = 30 So that 2x + 4x + 4 = 30 6x + 4 = 30 6x = 30 - 4 = 26 x = 26/6 which is NOT an integer.
