Question

what would be the next number in this series? 135 ... 45 ... 180 ... 60 ... 240 ... 80 ... ???

Answer 1

135/45=3
180=45 multiple by 4
180/60 =3
240=60multiple by 4
240/80=3
It is alternately divide by 3 and multiplying by 4
Hence =8 multiply 4 = 320

Answer 2

TO FIND

the next number in the series

GIVEN

the number series 135,45,180,60,240,80

SOLUTION

its a series so we have to decode it

let the unknown number be x

so,

135/45=3;    divided by next no quitiont=3

45*4=180;    next no is multiple of 4 of previous nuber

180/60=3;    divided by next no quitiont=3

60*4=240;    next no is multiple of 4 of previous number

the next should definetly be multiple of 4 of the previous number

so 80*4= 320

ANSWER

the next number in series is 320
