Use the graph below to write the explicit rule of the arithmetic sequence. f(n) = 3 + 5(n – 1)

f(n) = 2 + 3(n – 1)

f(n) = 4 + 3(n – 1)

f(n) = 3 + 3(n – 1)

Which equation and solution can be used to solve this problem? thirteen less than a number is sixteen. 13-n=16: add 13 to both sides. the answer is 29. n+13=16: subtract 13 from both sides. the answer is 3. n+16=13 subtract 13 from both sides. the answer is 3. n-13=16: add 13 to both sides. the answer is 29.
