Hey there :)
We can find the common difference here as it is an arithmetic sequence.
The common difference between each term is:
We can find the unknown term by:
{easier way in this example}
OR
by the formula for finding the nth term
a₆ =
{a₆ because it is the 6th term to be found, (6-1) the nth term minus 1}
a₆ =
However this way is not essential here as the previous term is given.

maths questions can be solved using unitary method.
<u>Answer:</u>
(a) The total number of girls in the class are 48
(b) The total number of students that like maths are 80
(c) The total number of boys like maths are 45
<u>Solution:</u>
According to the question, of total students are boys
number of boys = × 120 = 72
Also, According to the question, of total students like maths
number of students = × 120 =80
(a) The total number of girls in the class = total number of students - total number of boys
total number of girls in the class = 120 - 72 = 48
(b) The total number of students that like maths are 80
(c) The total number of boys like maths = total number of students that like maths - total number of girls that like maths
total number of boys like maths = 80 - 35 = 45
What is unitary method?
The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
