4th term from the end of A.P: -11, -8, -5, ……….. 49 is *37404358
Question
4th term from the end of A.P: -11, -8, -5, ……….. 49 is *37404358
Solution
The given sequence is an Arithmetic Progression (A.P) where the common difference (d) is -8 - (-11) = 3.
The nth term of an A.P is given by the formula: a + (n-1)d
The nth term from the end of an A.P is given by the formula: l - (n-1)d, where l is the last term.
Here, the last term (l) is 49 and we are asked to find the 4th term from the end.
So, substituting the values into the formula, we get:
49 - (4-1)*3 = 49 - 9 = 40
So, the 4th term from the end of the A.P is 40.
