Answer:
-37x+26
Step-by-step explanation:
The x-coefficients have the sequence ...
-2, -7, -12, ...
which has first term -2 and common difference of (-7 -(-2)) = -5. Then the 8th x-coefficient is ...
-2 + (-5)(8 -1) = -37
__
The constants have the sequence ...
5, 8, 11, ...
which has first term 5 and common difference 8 -5 = 3. Then the 8th constant term is ...
5 +(3)(8 -1) = 26
The 8th term of the sequence is -37x +26.
_____
The general term of an arithmetic sequence with first term a1 and common difference d is ...
an = a1 +d(n -1)
In the above, we have used n=8 to find the 8th term.
Answer:
a=18
Step-by-step explanation:
-2a-10+a=-28
-1a-10=-28
+10 +10
-1a=-18
divide by -1
a=18
Answer:
It would be 20
Step-by-step explanation:
As we can see, the sequence starts from 5 and increases by three each time. In fact, one possible formula for that sequence could be:
Let's confirm the formula by evaluating the first 6 terms:
5(700)+(50)+(4)that’s how you write it
Okay so like, all you've gotta do is multiply 567 by 48 & add 1250. Leaving you with the answer of 28,466
