According to question,
2 (a) + 3(a +1) + 4(a+ 2) = 74
=> 2a + 3a + 3 + 4a + 8 = 74
=> 9a + 11 = 74
=> 9a = 63
=> a = 7
First integer = 7
Second integer = 7 +1 = 8
Third integer = 7 + 2 = 9
given
2x + 3(x+1) + 4(x+2) = 74
= 2x +3x +4x +3+8 = 74
= 9x = 74- 11
= 9x = 63
= x = 63/9 = 7
so the numbers are 7,8 and 9
