Match 1-5 with a-e. 1. the positive integers 2. an ordering of quantities 3. 2, 4, 8, 16, . ., 256 4. 1, 3, 5, 7, . . 5. no first term is available a. the natural numbers b. the reason the numbers . . -4, -2, 0, 2, 4, . . are not a sequence c. an example of a finite sequence d. an example of an infinite sequence e. a sequence

The answer for the problem shown above is: a-1, c-3, d-4, e-2, b-5
 a-1. By definition,  the positive integers are the natural numbers.
 2-e. By defintion, a sequence are also known as an ordering of quantities.
 c-3. The dots after the term  are missing, which means that the sequence is finite.
 d-4. The dots (...) means that the sequence is infinite.
 b-5. The numbers  are not a sequence because no first term is available.
