## anonymous one year ago The product of three consecutive whole numbers is 990. What is the sum of the three whole numbers ? A. 30 B. 33 C. 63 D. 96

Start with the sum of 30. Assume one number and start guessing.

hint: three consecutive natural numbers are like these: $\large n,\quad n + 1,\quad n + 2$ so your problem reads now: $\Large n \cdot \left( {n + 1} \right) \cdot \left( {n + 2} \right) = 990$

For example: Is 9 * 10 * 11 = 990? If not, Make a new assumption, and test it.
