1. create a 3 x 3 magic square using the numbers 9 – 17. find the magic sum of the square.
2. two consecutive numbers in the virahanka sequence are 987 and 1597. what are the next 2 numbers in the sequence? what are the previous 2 numbers in the sequence?
3. create a 3 x 3 magic square whose magic sum is 60?
4. if ab || cd, ∠ apq = 50° and ∠ prd = 130°, then find the measure of ∠ qpr.
5. find the value of x in both figures.

Explanation:

Problem 1

Step1: Find middle number

Middle number of 9-17 is 13 (magic square center).

Step2: Calculate magic sum

Magic sum = 3×center = 3×13 = 45.

Problem 2

Step1: Define Virahanka rule

Each term = sum of two prior terms.

Step2: Find next terms

Next1 = 987+1597=2584; Next2=1597+2584=4181.

Step3: Find previous terms

Prev1 = 1597-987=610; Prev2=987-610=377.

Problem 3

Step1: Find center number

Center = magic sum/3 = 60/3=20.

Step2: Choose consecutive numbers

Use 16-24 (middle=20).

Step3: Construct square

Arrange so rows/columns/diagonals sum to 60.

Problem 4

Answer:

45
