Sophie and Nik were computing the sum of the “second” 50 odd numbers (101+103+105+…+195+197+199), but had different approaches to solving the problem. Nik suggested that they could just add up pairs of numbers since 101+199=103+197=105+195=300.
Finish computing the sum 101+103+105+…+195+197+199 the way Nik would have got the answer
