Write the first five terms of the geometric sequence in which a1=64 and the common ratio is 5/4

natita [175]

Remember that finding terms in a geometric sequence is done by multiplying the previous term by a common ratio $r$ . For example, we can say:

$a_2 = a_1 r$

$a_3 = a_2 r = (a_1 r)r = a_1 r^2$

We have $a_1 = 64$ . To find $a_2$ , let's multiply this term by $\frac{5}{4}$ :

$a_2 = 64 \cdot \frac{5}{4} = 80$

Now, let's use this to find all of our other terms:

$a_3 = 80 \cdot \frac{5}{4} = 100$

$a_4 = 100 \cdot \frac{5}{4} = 125$

$a_5 = 125 \cdot \frac{5}{4} = \frac{625}{4}$

Thus, our terms are 64, 80, 100, 125, and (625/4).

A triangle has sides with links that are consecutive odds intergers .The perimeter of the triangle is a hunt is 144 cm what's th

Rasek [7]

Answer:

50cm

Step-by-step explanation:

If the sides are consecutive odd integers,

Let the smallest side=y

The other sides are y+2 and y+4

The perimeter=144cm

y+y+2+y+4=144

3y+6=144

3y=144-6

3y=138

y=138/3=46cm

Therefore, the largest side of the triangle:

y+4=46+4=50cm

Therefore, the largest side of the triangle is 50cm
