Directions to Solve

Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.


27.
3, 8, 13, 24, 41, ?
70
75
80
85
Answer: Option
Explanation:

The pattern followed is : nth term + (n + l)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.

3, 8, 13, 24, 41.

3 * 2 + 2 = 8
3 * 4 + 1 = 13
3 * 8 + 0 = 24
3 * 14 - 1 = 41
3 * 22 - 2 = 64.

Is this logic correct? Please tell me.

3+8+2 = 13.
13+8+3 = 24.
24+13+4 = 41.
41+24+5 = 70.
