Question

for 1/4, 2/5, 1, ------ the sixth term is -2. how?

Answer 1

Step-by-step explanation:

A.P.=1/4,2/5,1,.......

So,

a=1/4

and d=a2-a1=2/5-1/4=8-5/20=3/20

Hence,

sixth term=a6=a+5d

                      =1/4+5*3/20

                     =1/4+3/4

                     =4/4

                     =1

so,the sixth term is 1
