Answer: The prime numbers are 17 and 19.
Explanation:
Let the first number be x.
Therefore, the other numbers are: x +2, x+4, x+6
According to the question,
3(x+6) + 2(x) = 93
3x + 18 + 2x = 93
5x = 93 - 18
5x = 75
x = 75/5
x = 15
The numbers are:
1st :- 15
2nd :- 15 + 2 = 17
3rd :- 15 + 4 = 19
4th :- 15 + 6 = 21
The prime numbers are: 17 and 19.
