What is the next number in the sequence?

Question

440 450 90 100 20 30 ?

Answer Choices:

15, 8, 10, 5, 6, 3

Answer 1

The answer is 6.

Explanation:

The sequence goes by adding 10 and then dividing by 5, then repeats itself again and again.

Therefore, you get: 440 + 10 = 450, 450/5 = 90, 90 + 10 = 100, 100/5 = 20, 20 + 10 = 30, 30/ 5 = 6.

Answer 2

I find such a rule: a₁ = 440. a₂ = 440 + 10 = 450; a₃ = 450/5 = 90; a₄ = 90 + 10 = 100; a₅ = 100/5 = 20;

a₆ = 20 + 10 = 30 and at last a₇ = 30/5 = 6.

Answer: next term is 6
