485 You arrive at 485 by multiplying the difference in the numbers by 3,and adding to the number.
i.e 5 minus 1 = 4, 4 x 3 = 12 + 5 = 17, 12 x 3 = 36 + 17 = 53, 36 x 3 = 108 + 53 = 161, 108 x 3 = 324 + 161 = 485.

The answer is 485. The pattern is 3x+2 where x is the previous number. For example 3(1) + 2 = 5, 3(5) + 2 = 17, etc. So to figure out the next number you just multiply 3 by 161 and add 2 to get 485.
The seed number is 1, thereafter each number is 2 + (3 x the previous number). 2 + 3x1 = 5 2 + 3x5 = 17 2 + 3x17 = 53 2 + 3x53 = 161 2 + 3x161 = 485
140 becomes 161 when increased by 15%. To find this answer, simply divide 161 by 1.15.
161 can be divided into several numbers. If you're looking for a whole number, one answer could be 23. Therefor, the quotient would be 7.
