Question

next in the series
5, 18, 67, 260, ?

Answer 1

Answer:

I’m going to go with 67.

Distance between 5 and 7 is 2.

Distance between 7 and 11 is 4.

Distance between 11 and 19 is 8.

Distance between 19 and 35 is 16.

It appears that the distance between each number to the next is increasing by a multiple of 2.

2 (first distance) ➡️ From 5 to 7

2 x 2 = 4 (first distance x 2 = second distance) ➡️ From 7 to 11

2 x 4 = 8 (second distance x 2 = third distance) ➡️ From 11 to 19

2 x 8 = 16 (third distance x 2 = fourth distance) ➡️ From 19 to 35

What follows would be:

2 x 16 = 32 (fourth distance x 2 = fifth distance) ➡️ From 35 to 67.

So, to reiterate, the fifth number (I believe) would be 67.
