Question

15,0,25,10,35,?bwhat is the ans​

Answer 1

First term is 15.

Second term is calculated by subtracting 15 from first term.

i.e. 15 - 15 = 0

Third term is calculated by adding 25 in second term.

i.e. 0 + 25 = 25

Fourth term is calculated by subtracting 15 from third term.

i.e. 25 - 15 = 10

Fifth term is calculated by adding 25 in fourth term.

i.e. 10 + 25 = 35

We can clearly see the pattern that, once 15 is subtracted from the previous term and then 25 is added to the previous term to calculate the next term.

So, next term is 6th term can be calculated by subtracting 15 from the fifth term.

35 - 15 = 20

So, the answer is 20.
