Answer 2

Step-by-step explanation:

➵

$let \: the \: first \: number \: be \: x \\ then \: second \: no. = 4x \\ and \: third \: = 4x - 12 \\ ➱ \: x + 4x + (4x - 12) = 123 \\ 9x - 12 = 123 \\ 9x = 123 + 12 \\ x = \frac{135}{9} \\ x = 15 \\ hence \: first \: no. = 15$

$➱second \: no. = 4x \\ = 4 \times 15 \\ = 60 \\ ➱third \: no. = 4x - 12 \\ = 60 - 12 \\ = 48$
