The sum of 5 consecutive even numbers is 216. what is the third number in the sequence

Hello from MrBillDoesMath!

 NO solution possible!

Steps:

Let "n" be the first even number. We are told that

n + (n+2) + (n+4) + (n+6) + (n +8)  = 216

The third number, the value we want, is boldfaced above.

Simplify the above equation:

5n + ( 2 + 4 + 6 + 8 ) = 216   or

5n +  20  = 216  or

5n = 196

n = 196/5   is NOT an integer value.  This problem, as stated, has no solution.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
