In this question ,it is given that
The penny size of a nail indicates the length of the nail. The penny size
d is given by the literal equation

where n is the length (in inches) of the nail.
In the first part we have to solve for n .
And for that firt we add 2 to both sides

Now we divide both sides by 4, that is

Part b.
When d=3

When d =6, we will get

When d =10, we will get

No because the number 7 repeats no x-values can repeat.
Answer:
-1280
Step-by-step explanation:
Given a₁ = -10, n = 8, r =2
Required to find nᵗʰ term.
From the general formula: aₙ= a₁ (r)ⁿ⁻¹
Therefore nᵗʰ = -10(2)⁸⁻¹
= -10(2)⁷
= - 10(128)
= - 1280
