Answer:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding
−n=-9
to the previous term in the sequence gives the next term. In other words,
This is an arithmetic sequence since there is a common difference between each term. In this case, adding − 9 to the previous term in the sequence gives the next term. In other words, a n = a 1 + d ( n − 1 ) . Arithmetic Sequence: d = − 9 This is the formula of an arithmetic sequence. a n = a 1 + d ( n − 1 ) Substitute in the values of a 1 = 14 and d = − 9 . a n = 14 − 9 ( n − 1 ) Simplify each term. Tap for more steps... a n = 14 − 9 n + 9 Add 14 and 9 . a n = − 9 n + 23
