1/25 because the only number higher than 24 is 25 and you are choosing a number between 1 and 25

Use mathematical induction to prove that the statement is true for every positive integer n. 8 + 16 + 24 + . . . + 8n = 4n(n + 1

First show the statement holds for $n=1$ . The left hand side is just 8, and the right hand side is $4(1)(1+1)=8$ , so it's true.

Assume the statement holds for $n=k$ , i.e.

$8+16+\cdots+8(k-1)+8k=4k(k+1)$

and use this to show it holds for $n=k+1$ , i.e.

$8+16+\cdots+8(k-1)+8k+8(k+1)=4(k+1)(k+2)$

By the assumption above, you have

$\underbrace{8+16+\cdots+8(k-1)+8k}_{n=k}+8(k+1)=4k(k+1)+8(k+1)=4(k+1)(k+2)$

so the statement is true for all $n\ge1$ .

Answer:

5 $\frac{1}{2}$

Explanation:

1. Find a common denominator for the three fractions. A common denominator is a number all three numbers divide into evenly. The lowest common denominator for 4, 3, and 6 is 12.

2. Find the numerators. This can be done by multiplying the current numerators by however many times the old denominator goes into the new denominator.

4 goes into 12 3 times

3 goes into 12 4 times

6 goes into 12 2 times

1 x 3 = 3

2 x 4 = 8

1 x 6 = 6

So, the fractions become:

$1\frac{3}{12} + 2\frac{8}{12} + 1\frac{2}{12}$
