Find the 5th and 6th terms in the expansion of ( 2x - 1/2 )10. *

a =2x,b=-1/2 and n=10.5th term is 840x2 and de 6th tem is -252x5 *

fanking 4.03.11 - 08:12am
For the 6th term r = 5
for the 5th term r = 4

therefore
(10C4)(2x)5(-0.5)5 + (10C4)(2x)6(-0.5)4

-252x5 + 210x6

are the 5th and sixth term respectively. *
