The average of a set of four consecutive multiples of 8 is 44. A second series consists of six consecutive even numbers, where the smallest number is equal to the second smallest multiple from the first set. What is the largest number in the second series?
Correct Answer :
50
Solution :
The correct answer is 50.
Step 1: Find the four consecutive multiples of 8.
Let the four consecutive multiples of 8 be , , , and .
The average of these four numbers is given as 44.
Simplifying the numerator:
The four consecutive multiples of 8 are:
First multiple = 32
Second smallest multiple = 32 + 8 = 40
Third multiple = 32 + 16 = 48
Fourth multiple = 32 + 24 = 56
Step 2: Determine the numbers in the second series.
The second series consists of six consecutive even numbers.
The smallest number in this series is equal to the second smallest multiple from the first set, which is 40.
The six consecutive even numbers starting from 40 are:
40, 42, 44, 46, 48, 50
Step 3: Identify the largest number in the second series.
The 6th (largest) number in this series is 50.
