The tenth through thirteenth terms of an arithmetic sequence are given by a 10 = 47, ajj = 53,912 = 59, and a 13 = 65. Which formula can be used to find an?
A. an = 6n - 13
B. an = 6n + 37
Can = 6n +41
D. Un = 6n - 47
E. an = 6n-7

35 is an outlier

step-by-step explanation:

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
