1st let's calculate r the common ratio:
r = (-20)/4 = (100/-20) = -5
Value of nth term = a₁.rⁿ⁻¹, where a₁= 1st term and n, the rank
Value of nth term = 4r⁽⁷⁻¹⁾ = 4.(-5)⁶
Value of nth term = 62,500
Answer:
2x-3
Step-by-step explanation:
If you subtract 2x from 4x-3, you got 2x-3. This must be the answer you're looking for. Hope it helps!
-3.5(2 - 3n) - 2.5n
= -7 + 10.5n - 2.5n
= -7 + 8n
