Explanation:

Let first term be x
According to the question
x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 x + 12 + x + 14 = 400
8x + 56 = 400
8x = 344
x = 43
x + 14 = 43 + 14 = 57
The next set of eight consecutive odd number will start
with = 59
Required sum = 59 + 61 + 63 + 65 + 67 + 69 +71 + 73 = 528
