Question

Observe the following pattern,

1, 4, 7, 10, 13

What will be the next term?

• A. 16
• B. -16
• C. 15
• D. -15

Answer 1

The correct option is A

16

The pattern is: 1, 4, 7, 10, 13

The sequence following is 3n + 1

When n = 0, the value is 1. For n = 3, the value is 10 and so on.

For n = 5 (as n starts from 0), the value will be: 3(5) + 1 = 16.
