How do you complete the statement for the arithmetic sequence: 170 is the __ term of -4, 2, 8, ...?
This is an arithmetic sequence with first term
Hopefully this helps!
170 is the 30th term of the sequence -4, 2, 8, ...
First, you need to determine what the likely sequence is. With only the three given numbers, it looks like each one is the previous one plus 6. Algebraically, the sequence is
Now we can put in the value of 170 and solve for the placement in the sequence.
Because ‘29’ is the (n-1)th term in the series, the value of 170 is the 30th term in the series.
