Add a fixed number to each and every term of A.P. Wrtie the resulting numbers as a list.

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

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

IF 8th term of an A.P. is 15, then the sum of 15 terms is

Write the formula for finding number of terms in A.P

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

Each term of an A.P. is doubled. Is the resulting sequence also an A.P.? If it is, write its first term, common difference and n^(th) term.

The sum of 5^(th) and 9^(th) terms of A.P. is 72 and the sum of 7th and 12th terms is 97. Find the A.P.

Which term of the A.P. 24,21,18,… is the first negative?

The number of terms in an A.P is even the sum of the odd terms in it is 24 and that the even terms is 30. If the last terms exceeds the first term by 10 (1)/(2) , then the number of terms in the A.P is
