NTH TERM OF A SEQUENCE

Write the first three terms of the sequence in which the nth term is 5n - 4.

SOLUTION:

Using the given formula, we'll find the first three terms by substituting n by the nth term.

[tex]•[/tex] 1st term [tex]•[/tex]

[tex]5n - 4[/tex]

[tex]5(1) - 4[/tex]

[tex]5 - 4[/tex]

= 1 - first term

[tex]•[/tex] 2nd term [tex]•[/tex]

[tex]5n - 4[/tex]

[tex]5(2) - 4[/tex]

[tex]10 - 4[/tex]

= 6 - second term

[tex]•[/tex] 3rd term [tex]•[/tex]

[tex]5n - 4[/tex]

[tex]5(3) - 4[/tex]

[tex]15 - 4[/tex]
