Answer 1

274,258,233,197,148 is the descending order

and

148,197,233,258,274 is the ascending order

Answer 2

Answer:

283 is the required next number of the given series .

Step-by-step explanation:

Explanation:

Given in the question, 148 ,197 ,233,258, 274,

So we need to find the next number of this series.

Let the next number be x .

Step 1:

Here , we can see that, starting number is 148 and the next number is 197 On subtracting 148 and 197 we get,

⇒197- 148 =  49

And  49 can be written as $7^2$ .

Now , take 197 as a first number and subtract it from the next number which is 233.

⇒233 - 197 = 36 = $6^2$

Similarly ,

On subtracting 233 and 258 we get,

258- 233 = 25 = $5^2$

and on subtracting 258 and 274 we get,

⇒274 - 258 =  16 = $4^2$

Step 2:

From the above, we can see that, the differences between the numbers are $7^2,6^2,5^2,4^2$  in the square form.

So, from the above information we conclude that, the next difference between the two numbers is $3^2$  which is 9 .

Therefore,  On subtracting x and 274 we get 9 .

⇒x - 274 = 9

⇒ x = 283.

Final answer:

Hence , 283 is the next number of the given series.
