Question

The sum of three consecutive numbers of which s is the first number

Answer 1

Answer:

3(s + 1)

Step-by-step explanation:

The first number =       s

The second number = s + 1 , as this is consecutive to s

The third number =      s + 2, identical reason as above.

Adding the above, The sum = s + (s + 1) + (s + 2) = 3s + 3 = 3(s + 1)
