Answer 1

Answer:

9 can be wrong in the series

I am not sure about it

Answer 2

Solution :-

Logic :- Multiply by n and subtracting n .

Explanation :-

→ 9 × 5 - 5 = 45 - 5 = 40

→ 40 × 4 - 4 = 160 - 4 = 156

→ 156 × 3 - 3 = 468 - 3 = 465

→ 465 × 2 - 2 = 930 - 2 = 928

therefore, we can conclude that, 464 is wrong number in the series and 465 will be correct number .
