Answer 2

Answer:

Option (c) Multiplied by 5 is correct answer.

Step-by-step explanation:

Let us consider an AP: a, a+d, a+2d... where a is first term of progression and d is common difference.

Now, according to question, we will multiply terms by 5, so we get AP as,

5a, 5a+5d, 5a+5*2d...

=> 5a, 5a+5d, 5a+10d...

Now, we will subtract 2 from the AP, so we get AP as

5a-2, 5a+5d-2, 5a+10d-2...

And we can further write it as

5a-2, 5a-2+5d, 5a-2+10d...

And if we find common difference by now, then we get d' = (5a-2+5d) - (5a-2) = 5d

Hence, we get the common difference as 5th multiple of d. Therefore, we can say that common difference is multiplied by 5.
