The value of N is 289.
Step-by-step explanation:
A sequence of number is given with a missing number "N".
To find N, find which pattern is followed in the sequence:
The sequence goes on reducing with small number than the previous one.
so, finding the difference= 400-361= 39
361-324= 37
It is found that 39-37= 2.
37-2= 35 and follows as 33 and 31.
So, the next number N can be find by 324-N= 35
324-35= N
N= 289
check whether the next number is followed correctly or not,
289-256 must give 33 and 256-225 gives 31. So the N value is correct.
