The common difference is -5
right now, a₁₂ = 22
to get a₁, subtract 5 each time you subtract one from the subscript
so
a₁₁ = 17
a₁₀ = 12
a₉ = 7
a₈ = 2
a₇ = -3
a₆ = -8
a₅ = -13
a₄ = -18
a₃ = -23
a₂ = - 28
a₁ = -33
a₁ = -33
hope this helps
X+3x=8
x=8-3x is how far i could simplify
6800 is 6840 rounded to the nearest hundredth.
23/198 that is the simplified version
