Answer 1

def check_product_of_every_pair(lst):
    for i in range(0, len(lst) - 1, 2):
        product = lst[i] * lst[i + 1]
        print(str(lst[i]) + " * " + str(lst[i + 1]) + " = " + str(product))
        if not product in lst:
            return False

    return True

list1 = [2, 3, 6, 5, 30, 0]  # Adjacent pairs: (2, 3), (6, 5), (30, 0)
print(check_product_of_every_pair(list1))  

list2 = [2, 3, 6, 5, 30, 7]  # Adjacent pairs: (2, 3), (6, 5), (30, 7)
print(check_product_of_every_pair(list2))

2 * 3 = 6
6 * 5 = 30
30 * 0 = 0
True
2 * 3 = 6
