Answer:
t(n) = 8n - 359
Step-by-step explanation:
t(n) = t1 + (n - 1)(d)
t(n) = -351 + (n - 1)(8)
t(n) = -351 + 8n - 8
t(n) = 8n - 359
The fastest way is to just use a scientific calculator.
To do it without a calculator, use prime factorization.
I'll only do the second one which is the answer.
27 x 8
= 3^3 x 2^3 = 6^3
Which is a perfect cube.
