Question

For each sequence, find the first 4 terms and the 10th term.

a.) n + 5
b.) 2n – 1​

Answer 1

For these, n is equal to the term you want. So you substitute the number in for whichever term you want. This means:

a) 1 (1st term) + 5 = 6
2 (2nd term) + 5 = 7
3 (3rd term) + 5 = 8
4 (4th term) + 5 = 9
10 (10th term) + 5 = 15

And so on for b (not going to keep writing the term, I’m sure you get that by now.

b) 2(1) - 1 = (2x1) - 1 = 1
2(2) - 1 = (2x2) - 1 = 3
2(3) - 1 = (2x3) - 1 = 5
2(4) - 1 = (2x4) - 1 = 7
2(10) - 1 = (2x10) - 1 = 19

Hope this helps :)

Answer 2

a. The Sequence are,  $6,7,8,9.....,15$

b. The Sequence are,  $1,3,5,7.......,9$

Sequence :

Given sequence is,

          $n+5$

Substitute $n=1,2,3,4.......10$ in above relation.

Terms of above sequence is,

       $1+5=6\\\\2+5=7\\\\3+5=8\\\\4+5=9\\\\10+5=15$

Sequence are,  $6,7,8,9.....,15$

Given sequence is,

                $2n-1$

Substitute $n=1,2,3,4.......10$ in above relation.

               $2-1=1\\\\4-1=3\\\\6-1=5\\\\8-1=7\\\\20-1=19$

Sequence are,  $1,3,5,7.......,9$
