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.
It is: nth term = 5-4n and so the next term will be -19
5 wholes and 3 over 11 as a decimal = 5.27275 3/11= 5 + (3 ÷ 11)= 5 + 0.2727= 5.2727
If you mean -1 3 7 11 15 then the nth term is 4n-5 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!
3 11
Term 1: 4 Term 2: 4 x 2 - 3 = 5 Term 3: 5 x 2 - 3 = 7 Term 4: 7 x 2 - 3 = 11 Term 5: 11 x 2 - 3 = 19 Term 6: 19 x 2 - 3 = 35
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.
2n+5
It is: nth term = 5-4n and so the next term will be -19
With each new term, you add a number n. This number is always odd, and increases by 2 with each term. So, starting with the first term, 2, you add n = 1 to get 3; add 3 to n = 3 to get 6; add 6 to 5 to get 11; and 7 to 11 to get 18. Here is the pattern written out: 2 + 1 = 3 3 + 3 = 6 6 + 5 = 11 11 + 7 = 18 ...
-5
2n + 1
The nth term of the sequence is 2n + 1.
