Use the way that kids use i.e trial and error method .

Solution:-

The set given by

\\ \rm\longmapsto \left\{32+n,\dfrac{n}{8},\sqrt{n+225}\right\}

Lets understand

  • See the first term any natural value will make it natural .

Come to 2nd one.

  • n should be a multiple of 8 to make it whole.

Come to third one

  • n should be a number which makes the sum a perfect square by which we get a natural no.We have to solve it w.r.t to 2nd one

Lets think

Nearest squares to 225 are 196 and 289

We can't take 196 as we have to take a positive one other wise it will come in terms of i.

Take 289

\\ \rm\longmapsto n+225=289

\\ \rm\longmapsto n=289-225=64

Its divisible by 8 .

Rewrite the set

\\ \rm\longmapsto \left\{64+32,\dfrac{64}{8},\sqrt{225+64}\right\}

\\ \rm\longmapsto \left\{96,8,\sqrt{289}\right\}

\\ \rm\longmapsto \left\{96,8,17\right\}

Hence n=64

2 tenths is equal to____ fifths
Sunny_sXe [5.5K]
To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.

2/10 = x/5

Now, we can use cross products to simplify this proportion.  Cross products sets the products of the numerator and denominator of separate fractions equal to one another.  It results in the equation:

(5)(2) = (10)(x)

Let's multiply out these numbers to further simplify the equation.

10 = 10x 

Finally, we have to divide both sides by 10, to get our variable x alone

x = 1

Therefore, 2 tenths is equal to 1 fifth.

What is the recursive rule for an=3n+5
inessss [21]

Answer:

Option d is correct.

Step-by-step explanation:

We have given a formula a_n=3n+5

We will put different values of n so, as to get a_n

from the given formula

When n =1  we get

a_1=3(1)+5=8

When n=2 we get

a_2=3(2)+5=11

When n=3 we get

a_3=3(3)+5=14

We can see that next term is 3 more than the previous term

Hence, a_1=8;a_n=a_{n-1}+3

Therefore, Option d is correct.
