The answer is 66. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
4 + 24 + 56 + 35 - 25 = 94
100-35
It is: 2 and 4/7 plus 4 and 2/5 = 244/35 or 6 and 34/35
few errors in your title: 2 plus 4 = 6 6 plus 9 = 15 10 plus 25 = 35 18 + 81 = 99
5/7 +4/5 = 25/35 + 28/35 = 53/35
25 plus 4 is 29: 25 + (1 = 26, 2 = 27, 3= 28, 4 = 29)
35: the other numbers are all squares of integers. 2^2 = 4, 3^2 = 9, 4^2 = 16, 5^2 = 25, 6^2 != 35. The last number in the sequence should be 36.

2/5 + 4/25 = 2x5/5x5 + 4/25 = 10/25 + 4/25 = (10 + 4)/25 = 14/25
2 plus 4/25 = 2.16
