Last question in a list of numbers the pattern increases by 0.001 as if the third number in the list is 0.046 what is the first number in the list EXPLAIN!!how you know

Answer 1

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...

Answer 2

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
