Which of the following choices is the explicit formula for the following geometric sequence?

1 answer:

3 0

Common ratio (r) can be found by dividing the second term by the first term.
0.02 / -0.1 = -0.2

an = a1 * r ^ (n - 1)
a1 = first term = -0.1
r = common ratio = -0.2

an = -0.1(-0.2)^(n - 1)...answer is C

Artyom0805 [142]

<u>Yes the first one is correct because n squared is n with the 2 above it and adding it to three gets your first answer and then the three on the outside means to multiply so your first response is correct.</u>

Remember solving inequalities is setting up two smaller inequalities one positive one negative. Also, when you divide or multiply by a negative number to solve for x the inequality changes over.
