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.

The mean and standard deviation of six observations are 8 and 4, respectively. If each observation is multiplied by 3, find the new mean and new standard deviation of the resulting observations

Insert five numbers between 8 and 26 such that the resulting sequence is an A.P.

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

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

By multiplying each term by non zero constant we get geometric sequence .
