each prize is RS. 20 less than its preceding prize; find the value of each prize. ​

Answer 1

Answer:

There are a total of 7 prizes and each prize is Rs 20 less than the previous prize. So let us take the first prize as Rs a. So, the second prize will be Rs a - 20 , third prize will be Rs a - 20 - 20 . Therefore, the prize money will form an A.P. with first term a and common difference −20.
