Final answer:
Use a while loop to multiply each odd number from 15 to 41 by initializing the product variable to 1 and the number variable to 15, multiply them, and increment the number by 2 on each iteration until the number exceeds 41.
Step-by-step explanation:
To answer the question using a while loop to calculate the product of the numbers 15, 17, 19, 21, up to 41, you would initiate the loop with the first number in the sequence (15) and continue to multiply by each subsequent odd number until you reach 41. Here is a pseudocode example of how this can be done:
product = 1
number = 15
while number <= 41:
product *= number
number += 2
print(product)
The variable product starts at 1 (since that's the identity for multiplication), and the variable number starts at 15. On each iteration of the loop, product is multiplied by the current value of number, and then number is incremented by 2 (to move to the next odd number). The loop ends when number exceeds 41. After the loop concludes, the final value of product is the product of all the odd numbers from 15 to 41.
