it goes by odd numbers, 2 + 3= 5, 5+5=10, 10 + 7=17
the rest of the pattern is 26, 37, and 50
17.6 = 17 6/10 = 17 6÷2/10÷2 = 17 3/5
It is: 2*10-3 = 17
2 5 10 17 26 37 50 65 82 (3+5+7+9+11...)
X2 + 10X - 13 = 17 add 13 to each side X2 + 10X = 30 halve the linear coefficient ( 10 ), square it and add it to both sides X2 + 10X + 25 = 30 + 25 factor on the left and gather terms on the right (X + 5)2 = 55 (X + 5)2 - 55 = 0 ---------------------------vertex form, (- 5, - 55 ), is the vertex -------------------------------------------[-------------------------------]
t(n) = 3(n-1) + 1, for n = 1, 2, 3, etc
2 9 5 13 10 19 17
Pattern: +7,-4,+8,-3,+9,-2... Pattern continuation: +10,-1,+11,*0,+12,+1 17+10=27
27
2 9 5 13 10 19 17 27 26 37 37
To find the pattern, simply look for the difference in the first two numbers, then the following pair of numbers, etc. 2 9 5 13 10 19 17 2 + 7 = 9 9 - 4 = 5 5 + 8 = 13 13 - 3 = 10 10 + 9 = 19 19 - 2 = 17 The pattern is +7, -4, +8, -3, +9, -2...
One.
10/17/2 is ambiguous. (10/17)/2 = 10/34 = 0.2941 (approx) while 10/(17/2) = 20/17 = 1.1765 (approx)
27 BUT, as far as I can tell, it does not complete the sequence which can continue further.
27. But that continues the sequence, it does not complete it.
what is the mean of -10, -5, 2, 6, 17
17.6 = 17 6/10 = 17 6÷2/10÷2 = 17 3/5
Add 10 + 17 and then divide by 2. 27/2=13.5
