Which term of the sequence tn = 5n - 3 for n ≥ 1 is 607? Class 9

Question 1.

Which term of the sequence t_n = 5n - 3 for n ≥ 1 is 607? Class 9

Solution:

Given, t_n = 5n - 3 for n ≥ 1

Let t_n = 607

∴ 5n - 3 = 607

∴ 5n = 610

n $=\frac{610}{5}$

∴ n = 122

∴ 607 is the 122^nd term of the sequence.
