Use inductive reasoning to predict the next line in the sequence of computations. Use a calculator or perform the arithmetic by hand to determine whether your conjecture is correct.
\[
\begin{array}{r}
2=1 \times 2 \\
2+4=2 \times 3 \\
2+4+6=3 \times 4
\end{array}
\]
The next equation is
(Type an equation. Do not perform the calculation. Use the multiplication symbol in the math palette as needed)

Step 1 ：Observe the pattern in the given sequence of computations. The left side of each equation is the sum of the first n even numbers, and the right side of the equation is n times the next number.

Step 2 ：Following this pattern, the next line should be the sum of the first 4 even numbers equals 4 times the next number, which is 5.

Step 3 ：Calculate the sum of the first 4 even numbers: 2 + 4 + 6 + 8 = 20.

Step 4 ：Calculate 4 times the next number: 4 * 5 = 20.

Step 5 ：Confirm that the sum of the first 4 even numbers is equal to 4 times the next number.

Step 6 ：Thus, the next equation in the sequence is \(2 + 4 + 6 + 8 = 4 \times 5\).

Step 7 ：Final Answer: \(\boxed{2 + 4 + 6 + 8 = 4 \times 5}\)
