What is the formula for the Fibonacci sequence?
Fn = Fn-2 * Fn
Fn = Fn-1 - Fn-2
Fn = Fn-2 + Fn
Fn = Fn-1 + Fn-2
What is the value of F2 in the Fibonacci sequence?

What is the general formula for an arithmetic series?
Sn = a1 + (n-1)d
Sn = n * (a1 + an)
Sn = n/2 * (a1 + an)
Sn = n * d
In the arithmetic series formula, what does 'd' represent?
The first term
The number of terms
The last term
The common difference
What is the formula for a geometric sequence?
an = a1 + (n-1)d
an = a1 + n
an = a1 / r^(n-1)
an = a1 * r^(n-1)
What does 'r' represent in a geometric sequence?
The first term
The common ratio
The number of terms
The last term
What is the formula for the nth term of an arithmetic sequence?
an = n * d
an = a1 * r^(n-1)
an = a1 + (n-1)d
an = a1 + n
What is the sum of the first n terms of an arithmetic series?
Sn = a1 + an
Sn = n/2 * (2a1 + (n-1)d)
Sn = n * d
Sn = n * (a1 + an)
In the formula Sn = n/2 * (a1 + an), what does 'an' represent?
The number of terms
The last term
The common difference
The first term
What is the common difference in an arithmetic sequence?
The average of the terms
The difference between consecutive terms
The ratio of consecutive terms
The sum of the first and last terms
What is the formula for the sum of a geometric series?
Sn = a1 + an
Sn = n/2 * (a1 + an)
Sn = n * (a1 + an)
Sn = a1 * (1 - r^n) / (1 - r)
If the common ratio 'r' is greater than 1, what happens to the terms of a geometric sequence?
They decrease
They remain constant
They increase
