Suppose Ashley is x years old now, Alfonso is x + 8 years old now.
Five years ago Alfonso was three times as old as Ashley, that is: (x + 8) - 5 = 3(x - 5), solve the equation we get x = 9.
Ashley is 9 years old now.

The seventh term of the following sequence 1, 2, 4, is 64.
common ratio = 4/2 = 2/1 = 2
7th term = 1*2^(7 - 1) = 2^6 = 64
