The Correct Option is C
Solution and Explanation
The perfect squares that end in 6 are:
- 42 = 16
- 62 = 36
- 142 = 196
- 162 = 256
- 242 = 576
These are the first five perfect squares ending in 6. Now, calculate their average:
Average = $\frac{16 + 36 + 196 + 256 + 576}{5}$Average = $\frac{1080}{5}$
Thus, the average is 216.
Therefore, the correct answer is (c) 216
