Directions (64 and 65): In the given series, pick the ODD NUMBER OUT
that does not follow the sequence / pattern of the series.
2, 9, 28, 65, 126, 216
9
28
65
126
216
Solution
The pattern is:
${{1}^{3}}+1=2$
${{2}^{3}}+1=9$
${{3}^{3}}+1=28$
${{4}^{3}}+1=65$
${{5}^{3}}+1=126$
${{6}^{3}}+1=216+1=217$
It should be 217 in place of 216.
