2n+4/2 term 1 = 3 term 2 = 4 term 3 = 5 term 4 = 6
3 + 3n = 9 + 2n + 4n n = -2
The question seems to be incorrect because, if the definition is 2n + 3 then the third tern should be 9 and the fourth one 11. In that case, t(6) = 2*6 + 3 = 12+3 = 15
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
3n + 9 = 3(n + 3)
The nth term of the sequence is 2n + 1.
2n+4/2 term 1 = 3 term 2 = 4 term 3 = 5 term 4 = 6
Solve for n. 2n+3=0 2n=-3 n=-3/2
1st term= 3 2nd term = 5 Nth term = 2n+1 10th term= 21 = 2(10)+1
2n + 3 = 352n = 35 -32n = 32n = 32/2n = 16
3 + 3n = 9 + 2n + 4n n = -2
18n + 27 or 9(2n + 3)
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
