Let's break down the series and analyze the pattern:

- 60,

- increase by 20 to get 80

- decrease by 16 to get 64

- increase by 6 to get 70

- decrease by 2 to get 68

- decrease by 8 to get 60

- decrease by 10 to get 50

The pattern seems to involve alternating between increasing and decreasing by specific numbers. Let's say:

- 60 to 80 (+20)

- 80 to 64 (-16)

- 64 to 70 (+6)

- 70 to 68 (-2)

- 68 to 60 (-8)

- 60 to ? (+12, as the pattern alternates between - and +)

If you follow the alternating increase and decrease pattern, a logical increase by 12 should make the number after 60, 72.

?? Correct Answer: Option:1, 72
