To find the maximum sum from the given series, we need to iterate through the numbers from 1 to N and calculate the sum of each term in the series.

Let's break down the steps to solve this problem:

1. Read the number of test cases, T.

2. Iterate T times to process each test case.

3. Read the value of N for the current test case.

4. Initialize a variable, maxSum, to store the maximum sum.

5. Iterate from 1 to N, with a step size of 2, to consider only the odd numbers in the series.

6. Inside the loop, calculate the sum of the current term, K*(K+1), and add it to the maxSum if it is greater than zero.

7. Print the value of maxSum for the current test case.

8. Repeat steps 3-7 for each test case.

Here is the code implementation in Python:

```python
# Step 1
T = int(input())

# Step 2
for _ in range(T):
# Step 3
N = int(input())

# Step 4
maxSum = 0

# Step 5
for K in range(1, N+1, 2):
# Step 6
term = K * (K+1)
if term 0:
maxSum += term

# Step 7
print(maxSum)
```

For the given example input (2, 3, 5), the output will be 8 and 18 respectively.
