Question

Which of the following gives the missing term in the given pattern?

A230I, B250J, C270K, ?, E310M

• A. D290L
• B. D280L
• C. C290L
• D. D290N

Answer 1

The correct option is A D290L

The given pattern is A230I, B250J, C270K, ?, E310M.

Here, the first letters from the terms are in alphabetical order.

Hence, the first letter should be "D" in the missing term.

The fifth letter in the first term starts from I and is in alphabetical order in the following terms.

Hence, the fifth letter in the missing term should be "L".

The numbers in the terms are 230, 250, 270.

This is an increasing pattern.

Difference between the 1st and the 2nd terms = 250 - 230 = 20

Difference between the 2nd and the 3rd terms = 270 - 250 = 20

Hence, the numbers in the missing term should be 270 + 20 = 290

Hence, the missing term in the given pattern is D290L.
