Find the 76th term of the arithmetic sequence 16, 14, 12, ...

the answer is -136 :)

Step-by-step explanation: since you are trying to find the n-th term, which in this case is 76 you would plug it into the formula. substitute 16 as the ace of 1 as it is your first term. Now, find the common distance which by doing simple math (16-14) we know is 2. Substitute the terms into the formula.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
