The sum of the first n consecutive even numbers can be found using S = n2 + n. What is the value of n when the sum is 272?

n>2

Step-by-step explanation:

The sum of the first n consecutive even numbers can be found using S = n2 + n, where n > 2.

Step-by-step explanation:

x = -2

y = 2

Step-by-step explanation:

3x  - 4y = -14 (I)

3x + 2y = -2 (II)

Multiply equation (II) by (-1) and then add. Now, x will be eliminated and you can find the value of y

(I)*(-1)           -3x + 4y = 14

(II)               3x + 2y =  -2        {Now, add}

                         6y = 12

                          y = 12/6

                        y = 2

Plugin y = 2 in equation (I)

3x - 4*2 = -14    {Add 8 to both sides}

3x - 8 = -14

    3x  = - 14 + 8    

    3x =  -6         {Divide both sides by 3}

      x = -6/3

       x = -2
