Answer: 1, 3, 5, 7, 9, . . . . , 37. Therefore, 361 is the sum of first 19 odd numbers.
Step-by-step explanation:

Let's do the bracket part first,
and solve further as shown,
One number is x
other number is 3x-10
x + 3x - 10 = 50
4x = 50 + 10
4x = 60
x = 60/4
x = 15 ← one number
the other number = 3x - 10 = 3*15 - 10 = 35
