=(15x^2-12x)+(25x-20)
=3x(5x-4)+5(5x-4)
=(5x-4)(3x+5

Answer:
C
Step-by-step explanation:
the explicit formula for an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
from the recursive formula in the form
=
+ d
given
=
- 7
with d = - 7 and a₁ = 4 , then explicit formula is
= 4 + (n - 1)(- 7)
