Question

What is the next number 18,24,36,56,86

Answer 1

Answer:

Step-by-step explanation:

the difference between 24 and 18 = 6

the difference between 24 and 36 = 12

the difference between 36 and 56 = 20               (i)

the difference between 56 and 86 = 30

Now,

the difference between 6 and 12 = 6

the difference between 12 and 20 = 8                 (ii)

the difference between 20 and 30 = 10

Again,

the difference between 6 and 8 = 2

the difference between 8 and 10 = 2                  (iii)

So the next number here would be 10 + 2 = 12

So now in we add 12 to 30 (ii) and we get 42.

Again we add 42 to 86 (i) and we get 128

So the answer required = 128
