Consider the sequence 4, 11, 18, 25, ... Give a closed formula for the nth term of the sequence (in the format dx+a for arithmetic, a*r^x for geometric): Is 2020 a term in the sequence? and the value of x (or the term) is How many terms does the sequence 4, 11, 18, 25,..., 249 have? Find the sum: 4 + 11 + 18 + 25 + ... +249.
