The first term is -5, the 50th term is -5-2*49=-103
The sum is the average of these terms times number of terms, which is (-5-103)/2*50=-2700
The amount the sister earns =x
The amount I earn = 2x
The amount the friend earns = 4x
4x + 2x + x = 210
7x = 210
x=30
Amount the sister earns = 30
Amount I earn = 2(30) = 60
Amount the friend earns = 4(30) = 120
