The nth term is 4n - 3
The nth term is 2n+5 and so the next number is 17
Add 4 to the previous number
n+4
It is: 2n+9
4 Four Qutro The correct answer is: The nth term is 4n + 1
The rule for the pattern 9, 13, 17, 21, 25 is that each number increases by 4 from the previous number. This can be expressed mathematically as: each term can be represented by the formula ( a_n = 9 + 4(n - 1) ), where ( n ) is the position of the term in the sequence. Thus, the pattern continues by adding 4 to the last number to generate the next one.
term n = 3n - 1 for n = 1, 2, 3, ...
The nth term is 2n+5 and so the next number is 17
13/17
There are infinitely many possible answers. The simplest, linear, rule is Un = 4n - 17 for n = 1, 2, 3, ...
Add 4 to the previous number
+8, +9, +10, (+11, +12, +13...)
n+4
It is: 2n+9
The rule is t(n) = 5 + 2*n, where n = 1, 2, 3, ...
4 Four Qutro The correct answer is: The nth term is 4n + 1
t(n) = 5 + 2*n
