Question

The next term in the sequence 10F, 11H, 13J, 16L, 20N, 25P, .. is

• A. 31R
• B. 41R
• C. 51R

Answer 1

The correct option is A 31R

The sequence can be split separately as alphabets and numbers.
10,11,13,16, 20, 25
If we add 1 to the sequence we get 2nd term and we add 2 to the 2nd term we get 3rd term and so on. It can be shown as
10 + 1 = 11
11+ 2 = 13
13 + 3 = 16
16 + 4 = 20
20 + 5 = 25
and next term will be 25 + 6 = 31

For alphabets, the sequence is every alternate alphabet.
First alphabet taken is F, the next is H and so on.
So, for the given last term, 25P, the next alternate alphabet after P is R.
Hence, the next term in the sequence is 31R
