Question

Find the t 11 of the AP 4-9-14

Answer 1

ap= 4,9,14 so the common difference is =9-4=14-9 which is in this case 5
let the common difference be d then d=5
to find  the 11th term(i assume that the t 11 means 11th term)
        t11=a+(n-1)d
        t11=4+(10)5
        t11=54
ans 54

Answer 2

A1-4 and a2 -9
So find the distance 9-4--5
So we find the the 11 term of ap
An --a+(n-1)d
Find 11nth term n place 11
A11--4+(11-1)5
A11--4+(10)5
A11--4+50
A11--54 answer
