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 ?
Answer:
The length of the hypotenuse is 26 inches
Step-by-step explanation:
The leg(brace) attached to the wall is 10 inches
Perpendicular = 10 inches
Your surfboard sits on a leg that is 24 inches.
Base = 24 inches
Formula : 
Hypotenuse = 26
Hence the length of the hypotenuse is 26 inches
5 trial regions out of 8 total equals a five in eight chance. Exclusive. Same probability no matter what the last spin was.
