n+4
The nth term is 4n - 3
2n+5
This is an Arithmetic Series/Sequence. In general the nth term, A(n) = a + (n - 1)d....where a is the 1st term and d is the common difference. In this question, the 1st term equals 1 and the common difference is 4. Then the nth term, A(n) = 1 + (n - 1) x 4 = 1 + 4n - 4 = 4n - 3.
The nth term is 2n+5 and so the next number is 17
n+4
The nth term is 4n - 3
The nth term is 25-4n and so the next term will be 5
It is 4n+5 and so the next term will be 25
2n+5
(13*17-5)/9 = 24
27 There are two interwoven series. A) 2,5,10,17 2 + 3 = 5 : 5 + 5 = 10 : 10 + 7 = 17 Each term takes the previous term and adds increasing odd numbers starting with 3. B) 9,13,19....and then 27 9 + 4 = 13 : 13 + 6 = 19 : 19 + 8 = 27 Each term takes the previous term and adds increasing even numbers starting with 4.
5 == 5 ==
17
5.7647
502775 = 5 * 5 * 7 * 13 * 13 * 17 = 52 * 7 * 132 * 17
The least common multiple of the numbers 13, 17 and 5 is 1,105.
