2n+4/2 term 1 = 3 term 2 = 4 term 3 = 5 term 4 = 6
The Nth term of tn = 2n + 3 is 2N + 3. Replace (substitute) the n by the term number to get its value. t1 = 2 x 1 + 3 = 5 t2 = 2 x 2 + 3 = 7 t3 = 2 x 3 + 3 = 9 etc.
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
is eassy
1st term= 3 2nd term = 5 Nth term = 2n+1 10th term= 21 = 2(10)+1
2n+4/2 term 1 = 3 term 2 = 4 term 3 = 5 term 4 = 6
7+2n
Tenth term of 5n + 1 = 5*10 + 1 = 51
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
2n plus 5 n would be 7n and its impossible to solve the value of n.
2n + 3 = 352n = 35 -32n = 32n = 32/2n = 16
3n+5=2n+7 subtract 2n on both sides. n+5=7 subtract 5 to the other side. n=2 the answer to n is 2. Hoped that helped. (:
2(2n + 5) = 12 2n + 5 = 6 2n = 1 n = 1/2
The Nth term of tn = 2n + 3 is 2N + 3. Replace (substitute) the n by the term number to get its value. t1 = 2 x 1 + 3 = 5 t2 = 2 x 2 + 3 = 7 t3 = 2 x 3 + 3 = 9 etc.
Solve for n. 6 = 1 - 2n + 5 6 = 6 - 2n 2n = 0 n = 0 Check it. 6 = 1 - 0 + 5 It checks.
The nth term of the sequence is 2n + 1.
