Look at the sequence below. To get to the next term in the sequence, subtract 70 from the term before. 390, 320, 250, ...
Understand the Problem
The question is asking for the next term in a numerical sequence where each term is derived by subtracting 70 from the previous term. Therefore, we need to calculate the next number after 250 by following the established pattern.
Answer
The next term is $180$.
Answer for screen readers
The next term in the sequence is 180.
Steps to Solve
-
Identify the last term in the sequence The last term given in the sequence is 250.
-
Calculate the next term by subtracting 70 To find the next term, subtract 70 from the last term:
$$ 250 - 70 = 180 $$
- Write the next term in the sequence The next term after 250 is 180.
The next term in the sequence is 180.
More Information
This sequence is an arithmetic sequence where each term is derived by subtracting a constant value (70) from the preceding term. In practical applications, understanding sequences can help in various areas like finance (calculating depreciation) and computer science (algorithms).
Tips
- Forgetting to subtract the correct amount (70) from the last term.
- Confusing the sequence pattern; ensure to follow the established operation consistently.
