C

The pattern in the series is +2, +6, +6, +10, +10,…..and the missing term is 14+10=24

A

The pattern is -45,-35,-25…..hence missing term is 20-15=5

201/4

223/4

C

The pattern is *3/2, so missing number =131/2*3/2 =27/2*3/2 =201/4

B

The pattern is +5,+20,+80,+320 i.e (5*1)2, +(5*2)2,+(5*4)2,+(5*8)2,…..so the missing term is=427+(5*16)2=427+1280=1707
