What is a geometric sequence?

Back

A sequence where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

How do you find the common ratio in a geometric sequence?

Back

Divide any term by the previous term. For example, in the sequence -2, -10, -50, -250, the common ratio is -5.

What is the formula for the nth term of a geometric sequence?

Back

t(n) = a * r^(n-1), where 'a' is the first term and 'r' is the common ratio.

What is an arithmetic sequence?

Back

A sequence of numbers in which the difference between consecutive terms is constant, known as the common difference.

How do you find the common difference in an arithmetic sequence?

Back

Subtract any term from the previous term. For example, in the sequence 2, 8, 14, the common difference is 6.

What is the formula for the nth term of an arithmetic sequence?

Back

a(n) = a + (n-1)d, where 'a' is the first term and 'd' is the common difference.

What does the function f(x) = mx + b represent?

Back

It represents a linear function, where 'm' is the slope and 'b' is the y-intercept.

How do you evaluate a function at a specific point?

Back

Substitute the value of x into the function. For example, f(12) = 2(12) + 17 = 41.

What is the difference between arithmetic and geometric sequences?

Back

Arithmetic sequences have a common difference, while geometric sequences have a common ratio.
