Let the 3 consecutive numbers are x , x+1 , x+2. The sum of the three consecutive numbers are -57(given) . i.e. x+x+1+x+2 = -57 =3x+3 = -57 =3x = -57-3 =3x = -60 (or) x = -20 therefore the consecutive integers are -20 , -19 , -18 .
18, 19 and 20
18+19+20 = 57
37 +20 = 57
21.
57
The numbers are 57 and 59.
21 17+19+21 =57
18, 19, 20
They are: 57+59 = 116
21.
The numbers are 56, 57 and 58.
57 and 59
57
The numbers are 57 and 59.
The numbers are 55, and 57. Two consecutive integers have an odd sum.
21 17+19+21 =57
They are 28 and 29
18, 19, 20
The integers are 51, 53, 55 and 57.
The two odd integers are 57 and 59.
