Show that each of the progressions given is an AP. Find the first term , common difference and next term of given series
`(i) 9 ,15 , 21 , 27 . . . `

Text Solution

Verified by Experts

(i)` 9, 15, 21, 27, …`

`15 – 9 = 21 – 15 = 27 – 21 = 6`

so common difference `=6`

next term `= 27 + d = 27 + 6 = 33`
