Question

a programmer is writing a loop that increments an index by 2 each time it runs. the loop starts with the index at 1 on the first iteration. on the fourth iteration, the programmers loop index will be at

Explanation:

Step1: Identify the initial value and increment

Initial value = 1, increment = 2.

Step2: Calculate the number of increments

For the fourth - iteration, the number of increments is 4 - 1=3.

Step3: Calculate the total increment

Total increment = increment×number of increments = 2×3 = 6.

Step4: Calculate the loop index

Loop index = initial value+total increment = 1+6 = 7.

Answer:

7
