I was careless just now. Please resend it
Arrange "1,2,3,2,3,4,3,4,5" according to the rule, and calculate the sum of the first 100 numbers
The rules are as follows
1,2,3
2,3,4
4,5,6
.
33,34,35
34,
There are 100 numbers: the sum of every three items in a new sequence,
Is the arithmetic sequence with A1 = 6, an = 102, n = 33, d = 3
The sum of them is: 34 + [(6 + 102) * 33] / 2 = 36 + 1782 = 1816
