Answer:
193
Step-by-step explanation:
Let's "cheat" a little on this one
We know that the numbers are consecutive
so lets take the square root of 9312 to get close
√9312 = 96.4987046545
Consecutive numbers around 96.4987046545
96 * 97 = 9312
96 + 97 = 193
-------------------------------
The "correct" method would be to set up an equation
x(x + 1) = 9312
x² + x = 9312
x² + x - 9312 = 0
Then use the quadratic equation to solve for x
Which you can do if you're so inclined.
Me, I'm happy to have "cheated"
