There must be 67 marbles.
You seem to be asking what consecutive numbers are. Consecutive numbers are integers in order, with each one being exactly 1 higher than the previous one. To put it another way, each number is the next higher integer after the previous one. For example, 3, 4, 5, 6, 7 are consecutive numbers. One can also refer to consecutive even numbers, consecutive odd numbers, consecutive square numbers, etc. In each case, each number in the sequence is the next higher number of the specified kind after the previous one. For example, 12, 14, 16, 18 are consecutive even numbers.
the answer is 4

You multiply the previous number by consecutive numbers starting with 1.
If the pattern below following the rule starting with 10 every consecutive line has a number 1 less than the previous line how many marbles must be in the seventh line?

Consecutive integers are integers that follow in sequence. Each number is 1 more than the previous numbers.
