Answer: The sum of five consecutive even numbers for this sequence is 20n.
Step-by-step explanation:
Since we have given that
Number of consecutive even numbers = 5
Middle value = 4n
Since there are 5 consecutive even numbers:
4n-4,4n-2,4n,4n+2,4n+4
So, Sum of five consecutive even numbers would be

Hence, the sum of five consecutive even numbers for this sequence is 20n.
I'm not sure if I'm correct x>9
x² + 10x = 26
x² + 10x + 25 = 26 + 25
x² + 5x + 5x + 25 = 51
x(x) + x(5) + 5(x) + 5(5) = 51
x(x + 5) + 5(x + 5) = 51
(x + 5)(x + 5) = 51
(x + 5)² = 51
x + 5 = ±√(51)
- 5 - 5
x = -5 ± √(51)
x = -5 + √(51) or x = -5 - √(51)
