Question

1, 4, 19, 94, 469, 2344

I have no idea what the pattern rule is please help.

Answer 1

Answer:

1, 4, 19, 94, 469, 2344, 11719, 58594, 292969, 1464844, 7324219, 36621094, 183105469, 915527344, 4577636719, 22888183594, 114440917969, ...

heres all the numbers when u look at them every number has a 4 or a 9 so it would be theres always a 4 or 9 in the pattern

Step-by-step explanation:

Answer 2

Concept

We will first take the difference of the adjacent quantities and then try to analyze the obtained sequence after the subtraction.

Given

The given sequence of the numbers is as follows

1, 4, 19, 94, 469, 2344

Find

We have to find out the relation between the numbers of the given sequence.

Solution

Let’s first subtract the adjacent numbers, we get

1, 4, 19, 94, 469, 2344

4-1 = 3, 19-4 = 15, 94-19 = 75, 469-94 = 375, 2344-469 = 1875

That is, the obtained sequence is

3, 15, 75, 375, 1875

Analyzing the above sequence we see that each next number is multiple of 5 of the previous number. Therefore in general we can say that the next number can be obtained by subtracting the two previous quantities and then multiplying it by 5.

Hence the pattern is first subtracting and then multiplying it by 5.
