Answer 2

Answer:

$\Large{\underline{\underline{\bf{Option\:C:\:43}}}}$

Step-by-step explanation:

$\Large{\underline{\underline{\bf{Given:}}}}$

• The AP is 1, 4, 7, 10......52

$\Large{\underline{\underline{\bf{To\:Find:}}}}$

• 4th term from the end of the series

$\Large{\underline{\underline{\bf{Solution:}}}}$

➢ Common difference(d) of the AP = a₂ - a₁ = 4-1 = 3

➢ The nth term from the end of the series is given by the formula

    $a_n\:=\:l\:-\:(n-1)d$

    where l is the last term of the AP, l = 52

➢ Substituting the given datas, we get

    Fourth term from end = 52 - (4-1)3

    Fourth term from end = 52-9

    $\boxed{\bold{Fourth\:term\:from\:end\:=\:43}}$

$\Large{\underline{\underline{\bf{Notes:}}}}$

➢ An AP is a series of numbers which have a constant common difference between its two consecutive terms.

➢ Any term from the end can be found out by the formula

   $a_n\:=\:l\:-\:(n-1)d$
