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.

Answer:
Step-by-step explanation:
First, in order to get rid of the parenthesis, you need to multiply 2.5 with whatever is in the parenthesis.
Multiply 2.5 on each side of the equation like this:
(12.75 x 2.5) (24.50 x 2.5) =188.75
Once you're finished, you should get 61.25 and 31.875x =188.75
Now in order to find 'x' you will need to subtract 61.25 to each side of the equation like this:
61.25 - 61.25 = 0
188.75 - 61.25 = 127.5
So now your equation should look like this:
31.875x = 127.5
You have to divide 31.875 by each side now.
Once you divide them, your final answer should be 4.
so x = 4.
I really hope this helps! ^^
