Answer:
The numbers are 8, 15 and 45
Explanation:
In this question, we are told to find three numbers according to the information in the question.
Let’s say the first number is x
The second number is 1 less than twice the first, that is 2x-1
The third number is 3 times the second meaning 3(2x-1)
Now let’s sum the numbers up to give 68
x + 2x - 1 + 6x -3 = 68
9x -4 = 68
9x = 68 + 4
9x = 72
x = 72/9
x = 8
The second number is 2x -1 = 2(8) - 1 = 16- 1 = 15
The third number is three times the second = 3(15) = 45
