1st term = 1³ ÷ 1 = 1
2nd term = ( 1³ + 2³ ) ÷ ( 1 + 3 ) = ( 1 + 8 ) ÷ 4 = 9/4 = 2.25
3rd term = ( 9 + 3³ ) ÷ ( 4 + 5 ) = ( 9 + 27 ) ÷ 9 = 36/9 = 4
4th term = ( 36 + 4³ ) ÷ ( 9 + 7 ) = ( 36 + 64 ) ÷ 16 = 100/16 = 6.25
5th term = ( 100 + 5³ ) ÷ ( 16 + 9 ) = ( 100 + 125 ) ÷ 25 = 225/25 = 9
6th term = ( 225 + 6³ ) ÷ ( 25 + 11 ) = ( 225 + 216 ) ÷ 36 = 441/36 = 12.25
7th term = ( 441 + 7³ ) ÷ ( 36 + 13 ) = ( 441 + 343 ) ÷ 49 = 784/49 = 16
8th term = ( 784 + 8³ ) ÷ ( 49 + 15 ) = ( 784 + 512 ) ÷ 64 = 1296/64 = 20.25
9th term = ( 1296 + 9³ ) ÷ ( 64 + 17 ) = ( 1296 + 729 ) ÷ 81 = 2025/81 = 25
Sum = 1 + 2.25 + 4 + 6.25 + 9 + 12.25 + 16 + 20.25 + 25
= 96.
2nd term = ( 1³ + 2³ ) ÷ ( 1 + 3 ) = ( 1 + 8 ) ÷ 4 = 9/4 = 2.25
3rd term = ( 9 + 3³ ) ÷ ( 4 + 5 ) = ( 9 + 27 ) ÷ 9 = 36/9 = 4
4th term = ( 36 + 4³ ) ÷ ( 9 + 7 ) = ( 36 + 64 ) ÷ 16 = 100/16 = 6.25
5th term = ( 100 + 5³ ) ÷ ( 16 + 9 ) = ( 100 + 125 ) ÷ 25 = 225/25 = 9
6th term = ( 225 + 6³ ) ÷ ( 25 + 11 ) = ( 225 + 216 ) ÷ 36 = 441/36 = 12.25
7th term = ( 441 + 7³ ) ÷ ( 36 + 13 ) = ( 441 + 343 ) ÷ 49 = 784/49 = 16
8th term = ( 784 + 8³ ) ÷ ( 49 + 15 ) = ( 784 + 512 ) ÷ 64 = 1296/64 = 20.25
9th term = ( 1296 + 9³ ) ÷ ( 64 + 17 ) = ( 1296 + 729 ) ÷ 81 = 2025/81 = 25
Sum = 1 + 2.25 + 4 + 6.25 + 9 + 12.25 + 16 + 20.25 + 25
= 96.
