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.
Answer:
5x and 6x both have the letter x. Let's combine them! 5x+6x = 11x
y, y, and 3y all have the letter y. You can imagine y to be 1y, they're the same.
1y + 1y + 3y = 5y
4, 6, and 2 don't have any letters. 4 + 6 + 2 = 12
Now you have to put all the final terms together to get: 11x + 5y +12

Answer:
12 Shirts
9.65 times 12 is 115.8 plus 43 is 158.8
8.40 time 12 is 100.8 plus 58 is 158.8
