Write a rule for the sequence.
5, –4, –13, –22,…
• Start with –9 and add 5 repeatedly.
• Start with 5 and add 9 repeatedly.
• Start with 5 and subtract –9 repeatedly.
• Start with 5 and add –9 repeatedly.
AAAaannndd the bot gets it wrong yet again!
while the bot is correct, that was not one of the choices. The correct answer was
Start with 5 and add –9 repeatedly.
The correct answer is: Start with 5 and subtract –9 repeatedly.
To find the rule for the sequence 5, –4, –13, –22, ..., we need to identify the pattern within the numbers.
Looking at the sequence, we can see that each number is obtained by subtracting 9 from the previous number.
So, the correct rule for the sequence is: Start with 5 and subtract 9 repeatedly.
The correct answer is: Start with 5 and subtract 9 repeatedly.
The sequence is decreasing by 9 each time, so the rule is to subtract 9 from the previous term to get the next term. Therefore, the rule for the sequence is:
an = a1 + (n-1)d
where a1 = 5, d = -9, and n is the term number.
