Answer:
55
Step-by-step explanation:
13-10 = 3
19-13 = 6
31 - 19 = 12
x - 31 = 12 * 2
x = 24+31 = 55
Missing numbers are numbers that were overlooked in a given series of numbers with similar differences. Finding similar changes between those numbers and filling their missing values in their specific series and places is referred to as the process of writing the missing numbers.
The logic here is:
The difference between the consecutive numbers when multiplied by 2 gives the difference of next consecutive numbers as a product.
So, the sequence goes like 10, 13, 19, 31, N, 103
13-10 = 3
As the logic stated,
⇒ 13-10 = 3*2 = 6
⇒ 19-13 = 6*2 = 12
⇒ 31-19 = 12*2 = 24
⇒ N-31 = 12*2
N = 55
⇒ 55-31 = 24*2 = 48
