Three consecutive even integers are such that the square of the third is 76 more than the square of the second. Find the three i

Arada [10]

Let n represent the interger l, the three consective intergers are represented by

$n$

$n + 2$

$n + 4$

The second one represent

$(n + 2) {}^{2} + 76 =( n + 4) {}^{2}$

Simplify both sides

$n {}^{2} + 4n + 4 + 76 = {n}^{2} + 8n + 16$

${n}^{2} + 4n + 4 = {n}^{2} + 8n - 60$

$4n + 4 = 8n - 60$

$4n + 64= 8n$

$64= 4n$

$n = 16$

The intergers are 16,18,20

Next term in 2, 6, 18, 54, 162, . . .

Free_Kalibri [48]

The pattern is multiple the previous term by three. So you take 162 and multiply it by three and get 486 (3x162=486)

3x - 3 = 2x

Add 3 on both sides

3x - 3 + 3 = 2x + 3
3x = 2x + 3

Subtract 2x on both sides

3x - 2x = 2x + 3 - 2x
3x - 2x = 3
x = 3

So, your final answer is x = 3.
