If you have 100 riders in 2013, .....................................

205 riders in 2014, 

415 riders in 2015,

 835 riders in 2016

the 2020th term.......

100..........205.....415.....835......

a= 100

the pattern is that 100 + 105= 205

205+210= 415

415+420=835

835+840=1675

1675+1680=3355

3355+3360=6715

6715+6720=13435

13435+13440=26,875

the riders 2020= 26,875
