Answer 1

1) 111, 112

2) 12, 9

3) -12

4) 31, 32, 33

Explanation:

1) n + (n+1) = 223

2n + 1 = 223

2n=222

n = 111 numbers: 111, 112

2) n + (n-3) = 21

2n - 3 = 21

2n=24

n=12 numbers: 12, 9

3) 2*(n+5) = n-2

2n + 10 = n - 2

n = -12 number: -12

4) n + (n+1) + (n+2) = 96

3n + 3 = 96

3n = 93

n=31 numbers: 31, 32, 33
