Question

find the next term in given in number series 840,168, 42,14,7​

Answer 1

Answer: 5040 or 7

Step-by-step explanation: Firstly we must identify the sequence, so we must find the similarities between the numbers, so 7 and 14, well 14 is double 7, 42 and 14, well 42 is triple 14, 42 and 168, well 168 is quadruple of 42. So we have identified the pattern, you times it by 2, then 3, then 4, then 5, ect, so the next term will be by 6. So 840 x 6 = 5040.

The next term in the sequence is 5040.

If the sequence was the other way round though then it will just be 7 as if it goes x6, x 5, x 4, x 3, x 2, then the next one must be times 1.

So it could also be 7

Hope this helps.
