Un = 2n + 1 for n = 1, 2, 3, ...
so U22 = 2*22 + 1 = 45
If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19
This is arithmetic progression with common difference of minus three...Formula:First Term +[ (number of term you want-1)*(common difference which is negative 3)]ExampleFor the 3RD term: -5=1+[(3-1)*(-3)]=1+[-6]= -5For 5TH term: -11=1+[(5-1)*(-3)]=1+(-12)=-11.: For the 21st term:=1+[(21-1)*(-3)]=1+[-60]= -59:D
That would be -5.
The sequence 5, 8, 11, 14, 17 is an arithmetic progression where each term increases by 3. The first term (a) is 5, and the common difference (d) is 3. The nth term can be expressed using the formula: ( a_n = a + (n-1)d ). Therefore, the nth term is ( a_n = 5 + (n-1) \cdot 3 = 3n + 2 ).
It is: nth term = 5-4n and so the next term will be -19
Factor out each term to get: 225 = 15 * 15 = 3² * 5² 165 = 15 * 11 = 3 * 5 * 11 Then, the GCF is 3 * 5 = 15 since that is the greatest term which divides both 225 and 165!
If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19

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.
That would be -5.

The sequence 5, 8, 11, 14, 17 is an arithmetic progression where each term increases by 3. The first term (a) is 5, and the common difference (d) is 3. The nth term can be expressed using the formula: ( a_n = a + (n-1)d ). Therefore, the nth term is ( a_n = 5 + (n-1) \cdot 3 = 3n + 2 ).
It is: nth term = 5-4n and so the next term will be -19

2n + 1
The nth term of the sequence is 2n + 1.
