you replace the "n" with ahundred e.g... if it's 2n+1, you will go 2x100+ 1 which is 201
2n+3. If 5 is the first term, then it is 2n + 3 (2×1 = 2 + 3 = 5 and 2×2 + 3 = 7)
The nth term is: 5-2n
2n+4/2 term 1 = 3 term 2 = 4 term 3 = 5 term 4 = 6
5-2n=3 -2n=3-5 -2n=-2 n=1
2n+4: 6,8,10......104........204

The nth term of the sequence is 2n + 1.
2n+3. If 5 is the first term, then it is 2n + 3 (2×1 = 2 + 3 = 5 and 2×2 + 3 = 7)
The nth term is: 5-2n
1st term= 3 2nd term = 5 Nth term = 2n+1 10th term= 21 = 2(10)+1
The nth term is 2n+5 and so the next number is 17
2n+4/2 term 1 = 3 term 2 = 4 term 3 = 5 term 4 = 6
2n-1 to the tenth term = 1
2n+5
6=(1-2n)+5 6-5=(1-2n)+5-5 1=1-2n 1-1=1-1-2n 0=-2n 0/-2=-2n/-2 0=n
5-2n=3 -2n=3-5 -2n=-2 n=1
