The sum of five numbers is 655.
The average of the first two numbers is 77.
The third number is 123.
Formula Used:
Sum of numbers = Average × Number of terms
Average = Sum of numbers / Number of terms
Calculation:
Sum of the first two numbers = 77 × 2
Sum of the first two numbers = 154
Sum of the first three numbers = 154 + 123
Sum of the first three numbers = 277
Sum of the remaining two numbers = 655 - 277
Sum of the remaining two numbers = 378
Average of the remaining two numbers = 378 / 2
⇒ Average of the remaining two numbers = 189
The average of the remaining two numbers is 189.
