Salutations!
To find the nth term, you will be needing a formula.
[tex]a +(n-1) *d[/tex]
a stands for the first term (first number in the sequence)
d stands for the difference between two terms. (always remember to subtract from the 2nd term to the 1st term)
and the n is what we are going to find
so in your sequence: 5, 10, 15, 20
5 is a (as it is the first term)
d would be 5 ( 10 -5 =5)
[tex]a+(n-1)*d[/tex]
[tex]5+ (n-1) *5[/tex]
[tex]5+5n-5[/tex]
[tex]5n+0[/tex]
your nth term is [tex]5n+0[/tex]
Hope this helps!
Have a great day!
