Question

How many elements in the vector v=[3:2:17]?

a) 5
b) 8
c) 7
d) 9

Answer 1

The vector v=[3:2:17] has 8 elements in it since it starts at 3 and adds 2 incrementally until 17 is reached.

Step-by-step explanation:

The vector v=[3:2:17] is a sequence of numbers starting from 3, increasing by 2 each time, and ending at or before 17. To determine the number of elements in vector v, start with the first number which is 3 and add 2 continuously until you reach or surpass 17:

3, 5, 7, 9, 11, 13, 15, 17

Counting these numbers, we can see that there are 8 elements in the vector v. Therefore, the correct answer to how many elements are in the vector v is B) 8.
