Step-by-step explanation:

46 is the second smallest number of the sequence

Step-by-step explanation:

Let's write the sum of 4 consecutive numbers (starting at the value x) as:

x + (x + 1) + (x + 2) + (x + 3) = 186

Now group all the unknowns:

x + x + x + x + 1 + 2 +3 = 186

4 x + 6 = 186

4 x = 186 - 6

4 x = 180

x = 180/4

x = 45

Then the sequence was: 45, 46, 47, 48

and the second smallest number of the sequence s: 46
