Explicit: #a_n=1+(n-1)3#
Recursive: #a_n=a_(n-1)+3#

Explanation:

This is an arithmetic sequence. The explicit and recursive formula is given by:

#"Explicit:"# #a_n=a_1+(n-1)*d#

#"n= the number term you want to find"#

#a_1"=the first term"#

#"d=the common difference."#

#"Recursive:"# #a_n=a_(n-1)+d#

Plug in.
