ANSWER
After one value is removed:
Since all of the values are Integers, the sum here must be an integer.
Sum=(number)×(average).
Since the average =35177, and the sum must be an integer, the number of integers must be a multiple of 17.
For any evenly spaced set, average = median.
After one of the consecutive integers is removed, most of the remaining set will still be evenly spaced.
As a result, the average of the remaining set 37177 will still be close to the median.
Implication:
The number of integers =4×17=68, with the result that 35177 will be close to the median of the 68 mostly consecutive integers.
∴ Sum=68×35177=2408.
Original set:
Since 68 integers remain after one of the integers is removed, the original set contains 69 integers.
Sum of the first n positive integers =2(n)(n+1).
∴ Sum=69×270=2415.
Removed integer = original sum - sum after one integer is removed
=2415−2408=7.

ANSWER
A galvanometer can be converted into an ammeter by connecting a low resistance (called shunt resistance) in parallel to the galvanometer. Parallel resistance being small will draw most of the current and the combination will not effect the original current in the circuit.
