Answer 2

Answer:

Step-by-step explanation:

This question belongs to the Fibonacci series which may be difficult for someone but can be solved in another way also (which is mentioned below)

The differences between subsequent terms are: 0,2,12,20,20,30,56

These differences can be written as:

0= 1^2 - 1

2= 2^2 - 2

12= 3^2 + 3

20= 4^2 +  4

20= 5^2 - 5

30= 6^2 - 6

56= 7^2 + 7

So the next difference would be 8^2 + 8 = 72

Hence the answer is 153+72 = 225

I am uploading it on other websites too because I had a hard time solving this Question.
