Answer:

457

Step-by-step explanation:

The general term of an arithmetic sequence is given by ...

an = a1 +d(n -1)

where a1 is the first term (-26), and d is the common difference (7).

The 70th term of your sequence can be found by putting the numbers into this formula:

a70 = -26 +7(70 -1) = -26 +483

a70 = 457

The 70th term of the sequence is 457.
