Answer: 175
Explanation Step 1: Find the difference between consecutive terms 130 − 115 = 15 145 − 130 = 15 160 − 145 = 15 The series increases by 15 each time. Step 2: Find the next term Next term = 160 + 15 = 175
Answer: 24
Explanation 1 = 0 2 = 8 3 = 16 4 = ? Pattern: Each number is being mapped as: n = (n - 1) × 8 Let’s verify: - 1 → (1 - 1) × 8 = 0 × 8 = 0 - 2 → (2 - 1) × 8 = 1 × 8 = 8 - 3 → (3 - 1) × 8 = 2 × 8 = 16 - 4 → (4 - 1) × 8 = 3 × 8 = 24 So, 4 = 24
Answer: 1/8
Explanation This is a simple division series; each number is one-half of the previous number. In other terms to say, the number is divided by 2 successively to get the next result. 4/2 = 2 2/2 = 1 1/2 = 1/2 1/2/2 = 1/4 1/4/2 = 1/8 and so on.
Answer: 40000
Explanation Suppose the value of the house is X then 160 = 2_5 ×X 160 = 2_5 X 1_100 × X 160 × 500 2X 80000 = 2X X = 40000
Answer: 11
Explanation To find Σ(x - 1), first calculate (x - 1) for each value: (3 - 1) + (1 - 1) + (7 - 1) + (4 - 1) = 2 + 0 + 6 + 3 = 11

Answer: 7
Explanation 8 – even number - 22 – even number - 27 – odd number - 7 – odd number So based on even/odd, 8 and 22 are even; 27 and 7 are odd → not helpful. Now check prime numbers: - 7 – prime - 8 – not prime - 22 – not prime - 27 – not prime So 7 is the only prime number.
