Given,
AP : 2,5,8,11
To find,
17 th term of Ap
Solution,
Now , AP (Arithmetic Progression) is a sequence with constant difference between two consecutive numbers.
In this AP : 2,5,8,11
2 is the first term
2nd term - 1st term = 5 - 2 = 3
3rd term - 2nd term = 8 - 5 = 3
4th term - 3rd term = 11 - 8 = 3
So, the common difference = 3
So the nth term in AP can be found by this formula,
= a + (n − 1) × d
a = first term
n = nth term
d = common difference
So , = 2 + (17 - 1) x 3
= 2 + (16 x 3)
= 2 + 48
= 50
Hence, 17th term of AP 2,5,8,11 is 50.
