Find the missing term: 3, 8, 13, 24, 41, ?
Discuss
Answer & Solution
Answer: Option A
Solution:
The pattern followed is:
n the term + (n + 1)th term + (n + 1) = (n + 2)th term
Thus, 1st term + 2nd term + 2 = 3rd term;
2nd term + 3rd term + 3 = 4th term and so on.
So, missing term = 6th term = 4th term + 5th term + 5 = 24 + 41 + 5 = 70
