What is the next number
2, 9, 28, 65, ____
Answer & explanation
Correct answer: option 2
THE LOGIC;
(The next series form of cube of the numbers added by +1)
2, 9, 28, 65, ____
So,
2 = \( {1}^{3} \) +01
9 = \( {2}^{3} \) +01
28 = \( {3}^{3} \) +01
65 = \( {4}^{3} \) +01
And the next series should be cube of 5 with added +1:-
126 = \( {5}^{3} \) +01
