Answer: B
Work:
Since the general formula of an arithmetic sequence is f(n) = (the first term) + (common difference)*(n-1), you just plug in what was given to you in the problem to that equation. The first term is -20 and the common difference is +15 since the the increase from one term to the next is 15. Doing so produces the equation f(n) = -20 + 15(n-1), which is choice B.
X = original angle
3x = (90-x) - 14
3x = -x + 76
4x= 76
x = 19
The measure of the angle is 19 degrees
Of the sixteen possibilities only one is HHHT, so the probability is
