 Answer:
64
Step-by-step explanation:
Note that each new term of this geometric sequence is 2x the previous term.
If the sequence starts off as 2, 4, 8, 16, 32 ... , then the next term is 2(32) = 64.

Given : 2D + 1L = 100, 
And D + L = 70
This is a simultaneous equation can be solved as follows 
 2D + L = 100
 - D - L = -70
————————————-
 D - 0 = 30
i.e D (number of dudes) = 30
Therefore, since we already know the fraternity sold 70 tickets in total, 
70 -30 = 40 (the number of ladies attended)
