Terms of sequences

15,22,31,42,55
find next 3 terms and the formula also for the sequence

3 answers

the next three terms are 70,87,106. the pattern is adding consecutive odd numbers to each term.
ex: 15+7=22, 22+9=31, 31+11=42, 42+13=55 and so on.

So the formula for the nth term of the sequence is

10+4n+n^2
