All series have different between two sequence digits and these number are like as- (3, 5, 7, 9, 11, 13,) odd numbers.

01.
3 04.
5 09.
7 16.
9 23 (It should be 25 number because of the difference.
11 36 between the odd numbers coming sequence).

There is another way, guys!

1.
1+3 = 4.
4+5 = 9.
9+7 = 16.
16+9 = 25.

By adding consecutive odd numbers to the answer that you get above it we get this order. (23 is missed out so it is the odd one).

Each numbers should add with odd numbers, first number is 1 add with 3 we get 4 like wise we add 4 with 5, 9 with 7 etc.

23 is the odd man out.

1^2 + 2 ^2 + 3^2 + 4^2 + 5^2 + 6^2.

In this condition the values(series) is given.

Here 23 is unnecessary present here.

So 23 is the answer.

1 + 3 = 4,
4 + 5 = 9,
9 + 7 = 16,
16 + 9 = 28.

Ans + next odd number 16 + 9 = 28.

But here the answer is 23. so 23 is the wrong number.

Why can't it be 23?

The difference between them is odd and following a sequence like 3, 5, 7, 7, 9. So it can be 23 also I think.

1+3=4.

First and odd numbers add get 2nd number so 16+9=25 but answer non correct so there is in 23 that wrong answer 23.

1*1=1.
2*2=4.
3*3=9.
4*4=16.
5*5=25.
6*6=36.

23 is prime number and it has no square root so that the answer is 23.

23 is non divisible and else are divisible. So these are those questions that can be solved at first look.

1,4,9,16,23,25,36.... question.

1*1,2*2,3*3,4*4,5*5,.... missed value 23..... the answer is 23.
