A₁ = -8 This is the first term in an arithmetic sequence.
d = 3, the common difference
a(n) = a₁ + d(n-1)
a₇ = -8 + 3(7-1)
a₇ = -8 + 3(6)
a₇ = -8 + 18
a₇ = 10
To check:
a₁ = -8
a₂ = -8 + 3 = -5
a₃ = -5 + 3 = -2
a₄ = -2 + 3 = 1
a₅ = 1 + 3 = 4
a₆ = 4 + 3 = 7
a₇ = 7 + 3 = 10
Step-by-step explanation:
The rule is to add 5 to each number to make next number
1 4 9 16 21 26 31 36 41

436.8/62.08 = x/1
436.8/62.08=7.04
7.04/1 =7.0/1
Hope that help!:)
With no much there it is hard to answer this.
But I am pretty sure I was able to do it
It’s call :
Simplify the matrix.
you have to write it out in the same [ ] [ ] large boxes as the picture you added
Top roll [ -5 -4 ]
Bottom roll. [ -5 -10] + a = b =
The answer would be 2 2/3
