Dear student The logic used here is : We have to add 1 to the previous number and take square root to find 2nd number. Ex- 63 + 1 = 64 square root of 64 is 8 then, 8 +1 = 9 (square root is 3). Keep learning Team TR

The middle number is sum of first number and third number × 2. Like in set(21,51,15)
51= 21+ (15×2)
