If you were asked to find the 87th term in a sequence, which formula would you want to be given?
a) analog form
b) digital form
c) explicit form
d) recursive form,

C) explicit form

Step-by-step explanation:

Since the explicit form is written in terms of the number of the term, it would be the most useful to find the 87th term. To use the recursive form, you would have to know the 86th term.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
