Number Pattern Challenge: Continue the Sequence from 850,000, 750,000

Let's determine the sequence by following these steps:

• Step 1: Identify the common difference by subtracting the second term from the first term: $750,000 - 850,000 = -100,000$.
• Step 2: Recognize that the sequence progresses by subtracting 100,000 from each term to get the next term.
• Step 3: Apply the difference to find the next terms:
• Third term: $650,000 = 750,000 - 100,000$
• Fourth term: $550,000 = 650,000 - 100,000$
• Fifth term: $450,000 = 550,000 - 100,000$

Therefore, the completed sequence following the same pattern is $650,000, 550,000, 450,000$.

Given the choices, this corresponds to choice 1.
