The average of 25, 35, and 45 is:
30
45
40
35
35
Since the numbers are in an arithmetic progression (difference of 10 between consecutive terms), the average is simply the middle term, which is 35.
Three numbers are provided: 25, 35, and 45.

Since the numbers are in an arithmetic progression (difference of 10 between consecutive terms), the average is simply the middle term, which is 35.
Students often try to add all numbers and divide manually, which is unnecessary here because the sequence is symmetric.
Identify the data points
Identify the set of values for which the average is to be calculated: 25, 35, 45.
25,35,45
Sum the values
Add the given terms together to find the total sum.
25+35+45=105
Calculate the average
Divide the total sum by the count of terms (3) using the average formula.
3105тАЛ=35
D is correct because the sum of 25, 35, and 45 is 105, and dividing by 3 results in 35.
For any set of numbers in an Arithmetic Progression, the Mean is always equal to the Median. This trick saves significant time in Data Interpretation questions.
