Answer to Problem 1.1.1P
Grey counter=
Other counters=
Explanation of Solution
Given information:
Stages of counter
Calculation:
At stage 1,
Grey counter= 1, other counter= 3 (2(1) +1)
At stage 2,
Grey counter= 4, other counter= 5 (2(2) +1)
At stage 3,
Grey counter= 9, other counter=7 (2(3) +1)
Observing the pattern,
At stage n,
Grey counter=
b.
To write 2 different expression
b.
Answer to Problem 1.1.1P
Explanation of Solution
Given information:
Stages of counter
Calculation:
Grey counter=
Total number of counters= grey counter + other counter
Substituting values,
Total counters =
This is the first expression.
2nd expression:
Total values=
Hence, both expressions are correct as one expression is an expanded form of other expression.
