- 3What is the formula of an arithmetic sequence?an = a1 +(n-1) d
- 4What is the general term of the Arithmetic Sequence -5, -2, 1, 4, 7...?a1 = 5, d = 3
an = a1 +(n-1)d
an = -5 + (n-1) 3, distribute 3
an = -5 + 3n - 3
an = 3n - 8 - 5What term is -39 in sequence 33, 25, 17, 9, 1, -7...?an = -39, a1 = 33, d = -8
an = a1 +(n-1)d
-39 = 33 +(-8n) 8
-39 = 41 + (-8n)
-41-39 = -8n
-80 = -8n, find n
-80/-8 = -8n/-8
n = 10 - 6Find the 8th term of 9, 20, 31, 42,...n = 8
an = a1 + d (n-1)
an = 9 + 11 ( 8-1)
an = 9 + 77
an = 86 - 7Find the 12th term of 9, 20, 31, 42,...n = 12
an = a1 + d (n-1)
an = 9 + 11 (12-1)
an = 9 + 121
an = 130 - 8Find the 14th term of 9, 20, 31, 42,...n = 14
an = a1 + d(n-1)
an = 9 + 11 (14-1)
an = 9 + 143
an = 152 - 9Arithmetic or Not? 1,2,3,5,...Arithmetic
- 10Arithmetic or Not? -6, 42, -294, 2058Not
