The Second Answer:
12 : x
4 : 21
Cross Multiply
4x = 252
x = 63
Answer:
Explicit: a₁=61 aₙ=a₁ -3ₓ(n-1)
Recursive: a₁=61 aₙ=aₙ₋₁ - 3
Step-by-step explanation:
Explicit: a₁=61 aₙ=a₁ -3ₓ(n-1)
Recursive: a₁=61 aₙ=aₙ₋₁ - 3
Answer:
x=13
Step-by-step explanation:
Divide both sides by -5 then solve the equation for x
