It is: nth term = 7n-9
First put them in order:11, 12, 13, 15, 16, 26, 26.Then use your fingers the numbers at the opposite ends:11, 12, 13, 15, 16, 26, 26.Then keep moving in11, 12, 13, 15, 16, 26, 26.11, 12, 13, 15, 16, 26, 26.Until you come to the middle:11, 12, 13, 15, 16, 26, 26.So the median is 15.
n2 + 3n - 2
(13 + 15 + 26 + 11 + 26 + 16 + 12)/7 = 17 ====
The Least Common Multiple (LCM) of 12, 26, and 39 is 156.
Perimeter = 2*(L + B) = 2*(12 + 14) = 2*26 = 52 inches.Perimeter = 2*(L + B) = 2*(12 + 14) = 2*26 = 52 inches.Perimeter = 2*(L + B) = 2*(12 + 14) = 2*26 = 52 inches.Perimeter = 2*(L + B) = 2*(12 + 14) = 2*26 = 52 inches.
Here are the first five terms of a sequence. 12 19 26 33 40 Find an expression for the nth term of this sequence.
Expressed in terms of n, the nth term is equal to 7n - 2.
The nth term in this arithmetic sequence is an=26+(n-1)(-8).
It is: nth term = 6n-4
It is: nth term = 35-9n
Tn = 10 + n2
46n9
It is: 26-8n
[ 6n + 8 ] is.
It is: 26-6n
The common difference (d) between successive terms is -9. The first term (a) is 26 The formula for the nth term [a(n)] of an Arithmetic Series is , a + (n - 1)d. Inputting the values for a and d gives :- a(n) = 26 - 9(n - 1) = 26 - 9n + 9 = 35 - 9n......where n = 1,2,3......
t(n) = 4n2 - 4n + 2
