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.

If 4 is multiplied to each term of a G.P., then the resulting series is a-

The sum of three numbers in A.P. is 18. If 2, 2, 6 are added respectively to 1st, 2nd and 3rd numbers, the resulting numbers are in G.P. Find the numbers.

Let sigma be the standard deviation of n observations. Each of the n observation is multiplied by a constant c. Then the standard deviation of the resulting numbers is

If the numbers in ratio are multiplied or divided by any number other than zero, let's verify if the ratio remains the same.

Three terms are in G.P. Their product is 216. If 4 be added to the first term and 6 to the second term, the resulting numbers are in A.P. Obtain the terms in G.P.

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