The nth term is -4n+102.
Method:
To find the nth term (Tn) of the sequence, multiply n by the pattern of change in the sequence from left to right (-4). Then, substitute n for a term, for example, term 2. Follow the first step (-4n) which will give -8. Then you add or subtract to equal the number of that term (94). -8+x=94. x=102. Therefore, the formula for the nth term is -4n+102. To prove it, try with any term.
Term 3 (the number is 90).
3 x -4 = -12
-12 + 102 = 90
Tada!
the nth term of the sequence 98, 94, 88, 80 can be expressed as 98 - (n - 1) * 2.
89+84+90+94+98=455 455/5= 91 91 is the mean.
100 - 3n
420
94 and you skip it by 8's
87
The median is 94.
90% of 94= 90% * 94= 0.9 * 94= 84.6
The median is 86.
The GCF is 2.
average = 89% average = (94% + 84%)/2 = 89%
80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100
