well... start by writing down your info that is provided.

Goes up by 0.001

-.---, -.---, 0.046

so i think it should be 0.044...
x = first number

You add 0.001 to each number to find the next number:

third number = x + 0.001 + 0.001 = 0.046

x + 0.002 = 0.046

Subtact 0,002 to both sides

x = 0.044
