81=81•2/2=162/2
81 1/2=162/2+1/2
=163/2
So 81 1/2=163/2=81.5

Answer:
B. 135, 45, 15, 5...
Step-by-step explanation:
I'll go in order from 135 using the pattern shown (tᵇ/3)
135 / 3
135 = 120 + 15
135/3 = (120/3) + (15/3)
135/3 = 40 + 5
135/3 = 45
All four answer choices show this, so no elimination yet.
45 / 3
45 = 30 + 15
45/3 = (30/3) + (15/3)
45/3 = 10 + 5
45/3 = 15
A and D show 30 as term 3, so they are out.
15 / 3
15/3 = 5
C shows 2 as term 4, so that is also out.
This leaves B as the correct answer.
