Multiply or divide each term of AP by a fixed number and write the resulting numbers as a list.

Add a fixed number to each and every term of AP. Write the resulting numbers as a list.

Similarly subtract a fixed number from each and every term ofAP. Write the resulting numbers as a list.

Consider the first 10 positive integers. If we multiply each number by -1 and then add 1 to each number, the variance of the numbers so obtained is :

All the terms of an AP are natural numbers and the sum of the first 20 terms is greater than 1072 and lss than 1162.If the sixth term is 32, then

Insert five numbers between 8 and 26 such that the resulting sequence is in AP.

Insert 6 numbers between 3 and 24 so that the resulting sequence is an A.P.

The variance of 20 observations is 5. If each observation is multiplied by 2, find the new variance of the resulting observations.
