The question is asking you to solve for A

to determine the first, fourth and tenth term you simply put those values in for (n)

the first term you then be given by the equation A(1) = 12 + ((1)-1)(3)

A= 12

Same thing for 4th term A(4) = 12 + ((4)-1)(3)

A= 21

10th term: A(10) = 12 + ((10)-1)(3)

A= 39

∴ your answer is C

You are not done though.

You HAVE to divide -124 by 5.

so your mean should be -24.8 degrees feriheit,
