Find the 107 terms of sequence - 9,-5,-1,3,7

415

Step-by-step explanation:

the nth term of the sequence is - 13 + 4n

the sequence is an arithmetic progression with nth term a + (n - 1) d

a = - 9, d = a5 - a4 = 7 - 3 = 4

nth = - 9 + (n - 1) 4

= - 9 + 4n - 4

= - 13 + 4n

hence the 107th term; - 13 + 4*107

-13 + 428 = 415
