Start with 100. Subtract 1 from that. Then subtract 2 from the answer. Next 3 from the answer and so on.
More generally,
Un = 100 - n*(n-1)/2 for n = 1, 2, 3, . . .
To find 85 percent of 90, you first convert 85 percent to a decimal by dividing by 100, which gives you 0.85. Then, you multiply 0.85 by 90 to get the answer. Therefore, 85 percent of 90 is 76.5.
It is 85, the middle value, between 80 and 90.
Median of the set = arithmetic mean of 75 and 85 = 80
108 remainder 3 :D
Since 90 is a whole number, rounding 85 to 90 does result in a whole number.
85+85=170+90=260+100=360/4=90 Problem solved.
90.
The pattern decreases by a sequence of consecutive integers: the first decrease is by 1 (100 to 99), the second by 2 (99 to 97), the third by 3 (97 to 94), and the fourth by 4 (94 to 90). Following this rule, the next number in the sequence would decrease by 5, resulting in 85.

15% off of 90 dollars = 85% of 90 dollars = 90*85/100 = 76.50 dollars
divide percent by 100 to get decimal; that means move decimal 2 places to left for example 90% = 90/100 = 0.90 85%=85/100 = 0.85 77.8% = 77.8/100 = .778
It is 85, the middle value, between 80 and 90.
85 appears more than any number, so it is the mode.
It is about 85-90, or 95-100 degrees.
