nth term = 5 +8n
The next term is 45 because the numbers are increasing by increments of 3 5 7 9 and then 11

nth term = 5 +8n
The next term is 45 because the numbers are increasing by increments of 3 5 7 9 and then 11
The GCF is 9.
(18 + 36) + (45 - 27) = 54 + 18 = 72
18 and 36 is 18 23 and 29 is 1 4 5 and 20 is 1 18 36 and 45 is 9 so 18 and 36
5n+1
3n^2 - n + 1
To find the nth term of the sequence 3, 11, 25, 45, we first look for a pattern in the differences between the terms. The first differences are 8, 14, and 20, and the second differences are 6, 6, indicating that the sequence is quadratic. We can express the nth term as ( a_n = An^2 + Bn + C ). Solving for A, B, and C using the given terms, we find the nth term is ( a_n = 3n^2 - 3n + 3 ).
