Answer:
5
Step-by-step explanation:
SQ= 10
SO is half way so divide by 2
Answer:
234
Step-by-step explanation:
The sequence is, in fact, quadratic. It is described by the equation
.. a[n] = (n*(n -1))/2 +2
First differences are increasing, so the sequence will not be arithmetic. An arithmetic sequence has constant first differences.
Second differences are constant, so the sequence will not be geometric. A geometric sequence will have first-, second-, third-differences, and those to any level, that have the same constant ratio as the terms of the original sequence.
Take your original equation 
and multiply both sides by 
to remove the fractions. You are left with
So,
Update: There is no numerical answer that can be found without being given a value for either x or y
