Answer:
623 is the answer
Step-by-step explanation:
equation : 8X-1
8(1)-1 = 7
8(2)-1 = 15
8(3)-1 = 23
8(4)-1 = 31
8(78)-1 = 623
If you have a calculator I would suggest using that, but otherwise here's the process:
170
+130
--------
Add the zeros.
0
+0
-----
Add 70 and 30.
70
+30
------
Carry the 1 on the 10
Add 100, 100, and 100 (From the 10)
100
100
+100
--------
Add 300, 0, and 0.
300
0
+ 0
---------
The answer is 300.
n is an integer, so 2n+1 is also an integer. 8s+1 is equal to the square of 2n+1, so it's a square number.
2n+1 is an odd integer for any value of n. The square of an odd integer is always an odd integer. Therefore 8s+1=(2n+1)² is odd.
8s+1 is an odd square number.
