Let's assume the first even number in the sequence is "n", then the consecutive even numbers will be n, n+2, n+4, n+6, and n+8.
The sum of these numbers can be represented as:
n + (n+2) + (n+4) + (n+6) + (n+8) = 350
Combining like terms:
5n + 20 = 350
Subtracting 20 from both sides:
5n = 330
Dividing both sides by 5:
n = 66
Therefore, the first even number is 66.
The second even number in the sequence is 66 + 2 = 68.
And the second least number in the sequence is 68.
