119. un = (-n4 + 15n3 - 77n2 + 225n + 192)/6
312511 = 122 = 433 = 2744 = 25655 = 3125
It is 122.
122/1=122122/2=61122/61=2122/122=1
Whole numbers such as 122 are not normally converted into mixed numbers.
365 would be next because you multiply the last number by three then subtract one.
The differences between the pairs of numbers up to that point are 31, 32, 33, 34. If the difference between the fifth number and the sixth number is equal to 35, that would make the next number equal to 122 + 243 = 265.
The next number works out as 365
365.
122
== 49 == 144 = 122 121 = 112 100 = 102 81 = 92 64 = 82 Implies 122, 112, 102, 92, 82 So the next number should be 72 = 49. So, the next number is 49.
122
123
122
The pattern in the sequence is that each number is obtained by multiplying the previous number by 3 and subtracting 1. 1 x 3 - 1 = 2 2 x 3 - 1 = 5 5 x 3 - 1 = 14 14 x 3 - 1 = 41 41 x 3 - 1 = 122 Therefore, the next number in the sequence would be 122 x 3 - 1 = 365.
Let's see. 122 + 14 = 136. 136 + 14 = 150. 150 + 14 = ?
170. 82 + 19 = 101 101 + 21 = 122 122 + 23 = 145 145 + 25 = 170. Difference increases by 2 each time.
