Answer:
The next number in the sequence 6, 12, 15, 60, 65, … is 390. This is based on the following pattern:
The first and third terms are multiplied by 2 to get the second and fourth terms: 6 x 2 = 12, 15 x 4 = 60.
The second and fourth terms are increased by 3 and 5 respectively to get the third and fifth terms: 12 + 3 = 15, 60 + 5 = 65.
Following this pattern, the fifth term should be multiplied by 6 to get the sixth term: 65 x 6 = 390.
This question is a number series problem that tests the ability to identify and apply a mathematical rule to a sequence of numbers. There are different sources that provide similar questions and explanations, such as 1, 2, and 3.
Summary: The next number in the sequence 6, 12, 15, 60, 65, … is 390, based on a pattern of multiplication and addition.
