20 is.
Find the 7th term of the geometric sequence whose common ratio is 1/2 and whose first turn is 5
The 'n'th term is [ 4 - 3n ].
The 'n'th term is [ 4 - 3n ].
Starting with the number 4, applying the rule of multiplying by 2 and then subtracting 3 gives the following sequence: 4, 5, 7, 11, 19, 35. This pattern can be calculated as follows: 4 x 2 - 3 = 5, 5 x 2 - 3 = 7, 7 x 2 - 3 = 11, 11 x 2 - 3 = 19, 19 x 2 - 3 = 35.

2n+5
It is: 3n+2
The answer is 47 The first term has 3 added to it = 2 + 3 =5 The second term has 6 added to it = 5 + (3 x 2) =5 + 6 = 11 The 3rd term is = 11 + (6 x 2) = 11 + 12= 23 Hence the next one is = 23 + (12 x 2) = 23 + 24 = 47
The nth term is 2 + 3n.
The nth term is 3n+2 and so the next number will be 17
The sequence 2, 5, 8, 11 is an arithmetic sequence where the first term is 2 and the common difference is 3. The nth term can be expressed using the formula: ( a_n = 2 + (n - 1) \cdot 3 ). Simplifying this gives ( a_n = 3n - 1 ). Thus, the nth term is ( 3n - 1 ).
