Question

increments of seven ​

Answer 1

Answer:

Specific Learning Outcomes:  

Solve problems that involve finding powers of a number

Description of mathematics:  

In this problem students work with powers of numbers and, as a consequence, come to understand what is happening to the numbers.  

Students also see how an apparently enormous and difficult calculation can be broken down into manageable parts. The students should come to realise that there are only a limited number of unit digits obtained when 7 is raised to a power. Further,  these specific digits 'cycle round' as the power of 7 increases. This cycle is 7, 9, 3, 1, 7, 9, …

The same is true of the digit in the tens place.

Answer 2

Following are calculations to compute the increments of seven: ​

• The term increment describes the enhancement of the number that is described as the 1 increments, 2 increments, 3 increments..... n.
• The calculation to the increments:

let number is 1 then:

$\to$ 1 increments$= n+1=1+1=2$

$\to$ 2 increments $= n+2=1+2=3$

$\to$ 3 increments $= n+3=1+3=4$

Similarly calculating the increments of seven:

$\to 7,8,9,10,11............$

Therefore, the final answer is "7,8,9,10,11..."
