Find the `11^(th)`from the last term (towards the first term) of the AP : `10 , 7, 4, ... , 62.` |
|
Answer» We have `a = 10, d = (7-10) = -3, l = -62 and n = 11`. `therefore` 11th term from the end `= {l - (n-1) xx d}` ` = {-62 -(11-1) xx (-3)}` `= (-62 + 30) = -32.` Hence, the 11th term from the end of the given AP is -32. |
