What is the answer for: the sum of three consecutive odd numbers, the smaller of which is equal to 2n–1.

Step-by-step explanation:

Since, Here  the smaller number = 2n - 1

Since, Numbers are consecutive.

Therefore, remaining numbers are 2n - 1 + 2 , 2n - 1 + 2 + 2

= 2n +1, 2n +3

Thus, the sum of these all numbers = 2n - 1 + 2n + 1 + 2n +3

=    ( By equating the like terms)

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

yes. we do proportions in probabilities.
