Step-by-step explanation:
you cannot just put the actual numbers in and calculate ?
and you can't provide the correct problem statement, as it seems.
I assume you mean
an = 3n² - 1
a sequence starts with a1, so, n>=1
a1 = 3×1² - 1 = 3-1 = 2
a2 = 3×2² -1 = 3×4 - 1 = 12 - 1 = 11
a3 = 3×3² - 1 = 3×9 - 1 = 27 - 1 = 26
a4 = 3×4² - 1 = 3×16 - 1 = 48 - 1 = 47
a5 = 3×5² - 1 = 3×25 - 1 = 75 - 1 = 74
there, that is all there is to it. you really needed help with that ?
Part 1:
First figure out how many apples she has. She bought 3 bags, each bag holds 12 apples. 3 * 12 = 36. So she has 36 apples in total. She needs 8 apples to make one pie. We can divide this by the total number of apples to figure out how many pies she can make.
36 / 8 = 4.5
So she can make 4.5 pies, or since this is real-life context, she can only make 4 pies.
Part 2:
To make 6 pies, she needs to have 8 apples for each pie. 8 * 6 = 48. So she needs 48 apples. She only has 36 apples now, 48 - 36 = 12. So she needs to buy 12 more apples if she wants to make 6 pies. Each bag holds 12 apples, so she needs to buy 1 more bag of apples.

Answer:
B
Step-by-step explanation:
27 = 3^3
3 = 4x + 1
2 = 4x
x = 1/2
Answer:
x = 14
Step-by-step explanation:
This problem requires and understanding about interior sum of angles.
This is an irregular hexagon. so Total angle sum = 180*(6 - 2) = 720 degrees.
...
80 + 56 + 61 + 43 + 92 + 2x = 360
332 + 2x = 360
2x = 360 - 332
2x = 28
x = 14
or... 6*180 - (332 + 2x) = 720
748 - 2x = 720... x= 14
