Given progression is an AP
with
first term, a = 10
common difference, d = 14 - 10 = 4
let,
nth term a[n] = 102
then,
a[n] = a + (n-1) d
102 = 10 + (n-1) 4
102 = 10 + 4n -4
102 = 6 + 4n
4n = 102 - 6
4n = 96
n = 96/4
n = 24
therefore,
24th term of the progression is 102.

✿ Question :
- Which térm of prôgrëssion 10,14,18, ,,,,, is 102 ?
✿ Solutioń :
༗ Here :-
- a = 10
- d = 4
- a _n = 102
- n = ?
Formulα to be used :-
a_n = a + ( n - 1 ) d
So, let's sôlve :
ㅤㅤㅤㅤㅤ➨ 102 = 10 + ( n - 1) 4
ㅤㅤㅤㅤㅤ➨ 102 - 10 = (n - 1) 4
ㅤㅤㅤㅤㅤㅤ➨ 92 =( n - 1) 4
ㅤㅤㅤㅤㅤㅤ➨ 92/4= n -1
ㅤㅤㅤㅤㅤㅤㅤ➨ 23 = n -1
ㅤㅤㅤㅤㅤㅤㅤ➨ 23 + 1 = n
ㅤㅤㅤㅤㅤㅤㅤ➨ 24 = n
➣ Therefore, 102 will be 24th term of the progression.
