Answer: 14.7
Step-by-step explanation:
Data : 12,18
Total Number of Values, N = 2
Step 1 : Find 1 / N
1 / N = 1 / 2 = 0.5
Step 2 : Find mean
GM = ( 12 * 18 )^ 0.5
= 14.7
Consecutive numbers differ by one. So, if
is the first, the three numbers are

The sum of the first and third integer is

Answer:
262 and 263 are consecutive natural numbers whose sum is 525.
Step-by-step explanation:
Natural number are a subset of real numbers consisting in positive integers (i.e. 1, 2, 3, 525) and two natural numbers are consecutive when distance between each other is equal to 1. (
,
) We can interpret the statement mathematically by means of the following expression:



Where
,
,
.
This system is reduced to a single equation and solved afterwards:




Now we evaluate
and
to obtain the natural numbers:


262 and 263 are consecutive natural numbers whose sum is 525.
