n x (n +1) = 40 =n^2 + n = 40 This does not have a solution in integers Even without the algebra you can quickly note that 7x6 is 42 which is too much and 6x5 is 30 which is too little so there is no solution.
-10.3723 and -4.6277(rounded)
-10 and 4,
Let the numbers be a - 1, a and a+1. Adding we get 42. This means a-1+a+a+1 = 42 ie 3a = 42 Therefore, a =42/3 = 14. Hence the consecutive numbers are 13,14 and 15. you check yourself by adding these.
They are: 7 times 7 = 49
.4
They would be 30 and 12(30+12=42;30*12=360)*=This means times,or multiply by.
Just multiply 40 x 0, 40 x 1, 40 x 2, etc.
(2x - 1) + (2x + 1) + (2x + 3) = 45From which . . .6x + 3 = 456x = 42x = 7The numbers are 13, 15, and 17.

forty-fourth.
20 * 40 = 800
