Consider the following sequence.

${s}_{n}=2n-1$

(a) Find the first three terms of the sequence whose nth term is given.

${s}_{1}=$

${s}_{2}=$

${s}_{3}=$

(b) Classify the sequence as arithmetic, geometric, both, or neither. arithmetic, geometric bothneither

If arithmetic, give d, if geometric, give r, if both, give d followed by r. (If both, enter your answers as a comma-separated list. If neither, enter NONE.)
