Final answer:
To add together the 2nd, 4th, and 6th digit, first identify these digits. Add them together, then multiply the sum by 2 to get the final answer.
Step-by-step explanation:
To add together the 2nd, 4th, and 6th digit, we first need to identify these digits. For example, if we have the number 987654, the 2nd digit would be 8, the 4th digit would be 6, and the 6th digit would be 4. Adding these digits together, we get 8 + 6 + 4 = 18.
Now, to multiply this sum by 2, we simply multiply 18 by 2. Therefore, the final answer is 18 * 2 = 36.
