Answer
Missing term in the sequence = 36
Explanation
Looking at the sequence, we can see that it is a geometric progression.
And the general form for the nth term of an geometric progression is
aₙ = a (rⁿ⁻¹)
where
aₙ = nth term = 3rd term
a = first term = 4
n = number of terms = 3
r = common ratio = ratio of consecitive terms = (second term)/(first term) = (fifth term)/(fourth term) = (12/4) = (324/108) = 3
For the third term now,
aₙ = a (rⁿ⁻¹)
a₃ = 4 (3³⁻¹)
a₃ = 4 (3²)
a₃ = 4 (9)
a₃ = 36
Hope this Helps!!!
