Question

ab,bb,bc,cc,cd,?,de,ee,?,ef,FG,gh​

Answer 1

The answer will be: dd

Step-by-step explanation:

Let us look at the given series first.

Take the first two terms:

• ab, bb
• After a, comes b and so is the first term.
• The second letter b comes twice.

Take the 3rd and the 4th terms:

• bc, cc
• After b, comes c and so is the third term.
• The second letter c comes twice.

Now let us use the above process for the 5th and the 6th terms:

• cd, ?
• After c, comes d and so is the fifth term.
• The second letter d will come twice in the sixth term.
• Thus, ? = dd.

Answer: dd
