Question

Q6.The 6th term from the end of an A.P having first term 17 and total terms 22 is 65 . Find the common difference ​

Answer 1

Answer:

If the A.P has 22 terms, then the "6th term FROM END" will be the "17th term FROM THE START" (as the "22nd"(last) term will be "1st" FROM LAST, the "21st term will be the "2nd" FROM LAST, .......and so on.....the "17th" term will be "6th" FROM LAST)

Given 6th term From End (i.e 17th term From Start)=65

a+(17-1)d=65

17+16d=65 [given a=17]

16d=48

d=3
