Question

Which number complete this sequence 2 4 10 28 -----

Answer 1

2, 4, 10, 28, ?

Answer:

82

Explanation:

From 2 to 4

⟹ { (3 × 2 ) - 2 }

⟹ 6 - 2

⟹ 4

From 4 to 10

⟹ { ( 3 × 4 ) - 2 }

⟹ 12 - 2

⟹ 10

From 10 to 28

⟹ { ( 3 × 10 ) - 2 }

⟹ 30 - 2

⟹ 10

We are following a pattern :

next number = 3 × previous number - 2

Next number in the series :

⟹ ( 3 × 28 ) - 2

⟹ 84 - 2

⟹ 82

82 is the next Number.

Answer 2

☆Answer☆

2, 4, 10, 28 ....?

82 is the next number.

☆Explanation☆

The difference between 2 and 4 is 2.

The difference between 4 and 10 is 6 (3*2).

The difference between 10 and 28 is 18 (3*6).

Therefore the difference between 28 and the next

number should be 54 (3*18).

Hence, the answer is 82.
