In following sequence of 3 numbers

+25 , -20 , +15

is a complete sequence and a new sequence of numbers starts after it:-

-5 , +10 , ..........

in this we can clearly see that after 5 the number ten which is the double of 5

i,e., 5+5=10

and the sign of 10 is + because the sign of 5 was (-).

So for next it will be (-) as 10 has + sign.

and the number will be 15 as 10+5=15.

Hope it helped u buddy..
