# Use the given algebraic expression to complete the table of number patterns.

(i)Expression = 2n - 1

100th term (i.e. n = 100)

= 2(100) - 1

= 200 - 1

= 199

(ii)Expression = 3n + 2

5th term( i.e. n = 5)

= 3(5) + 2

= 15 + 2

= 17

10th terms(i.e.. n =10)

=3(10) + 2

=30 + 2

= 32

100th term( i.e. n = 100)

=3(100) + 2

= 300 + 2

= 302

(iii)Expression = 4n + 1

5th term( i.e. n = 5)

= 4(5) + 1

= 20 + 1

= 21

10th terms(i.e.. n =10)

=4(10) + 1

=40 + 1

= 41

100th term( i.e. n = 100)

=4(100) + 1

= 400 + 1

= 401

(iv)Expression = 7n + 20

5th term( i.e. n = 5)

= 7(5) + 20

= 35 + 20

= 55

10th terms(i.e.. n =10)

=7(10) + 20

=70 + 20

= 90

100th term( i.e. n = 100)

=7(100) + 20

= 700 + 20

= 720

(v)Expression = n2 + 1

5th term( i.e. n = 5)

= (5)2 + 1

= 25 + 1

= 26

10th terms(i.e.. n =10)

=(10)2 + 1

=100 + 1

= 101

So the Table is
