Question

Write the first five terms of a sequence. Don’t make your sequence too simple. Write both an explicit formula and a recursive formula for a general term in the sequence. Explain in detail how you found both formulas.

My answer is 15, 30, 45, 60, 75 I don't know how to do the rest please help.

Answer 1

a_n = 15n

a_1 = 15
a_n+1 = a_n + 15

Answer 2

write a recursive formula for the sequence 14,10 6,2

Answer 3

a_1 = 14

a_n = a_(n-1) - 4
