  • Q1
    What is the formula to find the sum of an arithmetic sequence?
    Sn = (n/2)(2a1 + nd)
    Sn = (n/2)(a1 + (n+1)d)
    Sn = (n/2)(a1 + (n-1)c)
    Sn = (n/2)(2a1 + (n-1)d)

  • Q2
    What is the formula to find the nth term of a geometric sequence?
    an = a1 + r^(n-1)
    an = a1 * r^n
    an = a1 + (n-1)r
    an = a1 * r^(n-1)

  • Q3
    What is the formula to find the sum of a finite geometric sequence?
    Sn = a1 * (1 - r^n) / (1 + r)
    Sn = a1 * (1 + r^n) / (1 - r)
    Sn = a1 + r^n / r
    Sn = a1 * (1 - r^n) / (1 - r)

  • Q4
    What is the formula to find the common ratio of a geometric sequence?
    r = (a1 + a2) / 2
    r = a1 * a2
    r = a2 / a1
    r = a1 / a2

  • Q5
    What is the formula to find the common difference of an arithmetic sequence?
    d = a1 + a2
    d = a2 - a1
    d = (a1 + a2)/2
    d = a1 - a2

  • Q6
    What is the formula to find the sum of a finite arithmetic sequence?
    Sn = (n/2)(a1 + an)
    Sn = (n/2)(2a1 + (n-1)d)
    Sn = (n/2)(a1 + (n-1)d)
    Sn = (n/2)(a1 + an - 1)
