First simplify the equation and next multiply the 20 with the x^2 and find a number that adds together to give you the middle
From the recursive rule, you can tell the initial value is 3 and the common ratio is 12. The explicit rule is always
.. (n-th term) = (initial value)*(common ratio)^(n -1)
Subsituting the values you know, you have
.. an = 3*12^(n-1)
What it is side ways i can help sory
The answer is 3/5.
Continue this pattern and you'll see that it follows this geometric sequence
Exact Form:
x = 34/7
Decimal Form:
x= 4. 857142
Mixed Number Form:
x= 4 6/7
