A Different Angle
What should replace the question mark in this series?
16, 06, 68, 88, ?, 98
16, 06, 68, 88, ?, 98
Hint
Try looking at the problem from a different angle (literally).Answer
Take the given series and rotate it by 180 degrees.It now becomes: 86, ?, 88, 89, 90, 91.
Clearly the number that is missing is 87.
So in the original series, replace the question mark with a rotated 87 which is approximated by L8 here:
16, 06, 68, 88, L8, 98
