Question

Which of these is a formula that can be used to determine the nth term of the sequence 15, 27, 39, 51,...?

Answer 1

Answer:

an= 3+12n

Step-by-step explanation: the sequence is 15,27,39,51 The first term is : a 1= 15 The common difference of this sequence : d= 27 - 15

The nth term of an arithmetic sequence is given by formula an= a + (n - 1 ) d . so a n for the sequence will be :

an =15+ (n-1) 12

an = (15)+12n - 12

an = 3 + 12n
