Question:

Options:

41

45

36

31

Correct Answer:

36

Explanation:

First 8 multiples of 8 is: 8, 16, 24, 32, 40, 48, 56, 64

Average = \(\frac{Sum of terms}{no. of terms}\)

Sum of terms = 8 + 16 + 24 + 32 + 40 + 48 + 56 + 64 = 8 (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8) = 8 × 36

Average = \(\frac{8 × 36}{8}\) = 36
