Question

Find the next term in the series.
20,8, 40, 24, 240, ?

​

Answer 1

Answer:192

Step-by-step explanation:

Here 8/20 is in ratio 2/5

24 /40 is in ratio 3/5

Therefore

x/240 should be in ratio (3/5 +1/5)

x/240 should be in ratio 4/5

So x = 4/5 *240 = 192

So the missing term is 192

Answer 2

The right answer is ...

72

Step-by-step explanation:

We have terms 20,8,40, 24,240, ?

First term= 20

second term= 8

third term is calculated as below:

= first term×second term/4= 20×8/4= 40

Now forth term is three times the second term

= 8×3= 24

fifth term is calculated in same way as third term

= third term×fourth term/4

=40×24/4= 240

and sixth term shall be three times fourth term

i.e

=24×3= 72

Hence the answer to this question is 72.
