Write the formula for the sum of 7 consecutive numbers if the first number is m. \

Step-by-step explanation:

If you have an odd number of consecutive numbers, the middle number should be x. So 7 of them would be written as

(x - 3)+(x - 2) + (x - 1) + x + (x + 1) + (x + 2) + (x+3)

That way all you are left with is 7x because the integers cancel.

That is not your question

You question is

Sum = m+(m + 1)  + (m + 2) + (m + 3) + (m + 4) + (m + 5) + (m + 6)

Hello!

We can say what the formula is:

We need a formula to add 7 consecutive numbers, m being the first one.

So, we have:

Now, let's simplify, joining the m and the numbers:

So, the formula is:

Let's say that m is 2. So, we substitute in the first non-simplified formula:

Now, we put it in the simplified formula, and it should give the same result:

It was confirmed. We conclude, once again, that the formula is:
