Sequence: 1,7,49,343,??,16807, 7th term, 8th....
we notice that:
1st term = 1 or 7^0
2nd term = 7 or 7^1
3rd term =49 or 7^2
4th term = 343 or 7^3
5th term = ?? or 7^4 (=2401)
6th term = 16807 or 7^5
7th term = 117 647 or 7^6
nth term = (7)^(n-1)
Answer:
<u>the order in which the ratio is drawn should be the same as listed.</u>
Explanation:
What this means is that since a ratio compares the sizes of two numbers (eg 4:2 or 4 ratios 2 or 
), it would be wrong to change the order of a ratio when drawn in a diagram.
For example, changing the order to (2:4 or 2 ratios 4), which then because 
not . Hence, it is important to remember that diagram of the ratio of two or more quantities should be the same as listed.
ik=30.5 because 49 - 12 = 37.5 and 37.5/2+12=30.5
