The pattern above follows a geometric progression. Each number in the sequence is a multiple of the other. This is evident because:
0.2 ÷ 0.04 = 5
1 ÷ 0.2 = 5
5 ÷ 1 = 5
∴ this is evidence that the each number in the series is 5 times that of the number that precedes it. Based on this confirmation then the other two numbers in the sequence are ( 5 × 5) and (5 × 5 × 5).
Thus the completed series looks like 0.04, 0.2, 1, 5, 25, 125
