Best Answer

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.

The nth term is: 5-2n

Nth term With the nth term you substitute the n for the term number (e.g. 50) so the 50th term in 2n+3 would be 2x50+3=103

2n+3. If 5 is the first term, then it is 2n + 3 (2×1 = 2 + 3 = 5 and 2×2 + 3 = 7)

Un = (-1)n*(2n - 1)

(2n-1)(-1)n

The nth term is: 5-2n

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

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

Nth term With the nth term you substitute the n for the term number (e.g. 50) so the 50th term in 2n+3 would be 2x50+3=103

t(n) = 3*2n-1 Or just 3*2n

2n+3. If 5 is the first term, then it is 2n + 3 (2×1 = 2 + 3 = 5 and 2×2 + 3 = 7)

This is an arithmetic sequence with initial term a = 3 and common difference d = 2. Using the nth term formula for arithmetic sequences an = a + (n - 1)d we get an = 3 + (n - 1)(2) = 2n - 2 + 3 = 2n + 1.

20 - (3 * (n - 1))
