For Exercises 1–4, make reasonable conjectures for the next three numbers or letters in the sequence.
1. 3 4 6 7 9 10 12 13 15 16 ___ ___ ___
To find: The next three numbers or letters in the sequence by making reasonable conjecture.
Answer to Problem 1RE
The next number in the given sequence is 3 4 6 7 9 10 12 13 15 16 18 19 21.
Explanation of Solution
Result used:
Inductive reasoning is the process of reasoning to a general conclusion through observations of specific cases.
Induction often involves observing a pattern and from that pattern predicting a conclusion.
Calculation:
The sequence is 3 4 6 7 9 10 12 13 15 16.
From the given sequence, it is observed that the difference between the first and the second number is 1.
The difference of second and third number is 2
The difference of third and the fourth number is 1.
Therefore, it can be concluded that the difference of the numbers are changing alternatively by 1 and 2. This is the conjecture for given sequence.
The difference between the tenth and eleventh number in the sequence will be 2 and the required number is 18.
The next difference will be 1 and the next number is 19.
Similarly, the last number is 21.
Thus, the pattern of the sequence is 3 4 6 7 9 10 12 13 15 16 18 19 21.

- 2. Consider the following argument: (a) Seabiscuit is a thoroughbred. Seabiscuit is very fast. Every very fast racehorse can win the race. .. Therefore, some thoroughbred racehorse can win the race. Let us define the following predicates, whose domain is racehorses: T(x) x is a thoroughbred F(x) x is very fast R(x) x can win the race : Write the above argument in logical symbols using these predicates. (b) Prove the argument using the rules of inference. Do not make use of conditional proof. (c) Rewrite the proof using full sentences, avoiding logical symbols.
