Answer:
6n
Step-by-step explanation:
given 2n is the middle no. of the 3 consecutive whole numbers,
=> the 3 no.s are (2n-1), 2n,(2n+1)
so their sum = (2n-1)+2n+(2n+1)
= 2n+2n+2n
= 6n

The sum of the 3 consecutive whole numbers with 2n as the middle number is 6n.
Step-by-step explanation:
We know that, each whole number is increased by 1 than the previous whole number.
Since the middle number is 2n, then
- the previous whole number is 2n - 1 and
- the next whole number is 2n + 1.
Thus the required sum
= (2n - 1) + 2n + (2n + 1)
= 2n - 1 + 2n + 2n + 1
= 6n
