Direction: Information about three values have been given, you have to calculate the value of all three quantities and answer the question accordingly.
Quantity I. 2, 3, 4, 15, 56, X
Quantity II. 3, 2, 7, 16, 71, Y
Quantity III. 14, 16, 28, 64, 144, Z
X > Y > Z
X < Y > Z
X < Y < Z
X = Y > Z
X = Y < Z
Alright, here’s how we break it down:
Quantity I: 2, 3, 4, 15, 56, X
- Look at the pattern:
- 2×1+1=3
- 3×1+1=4
- 4×3+3=15
- 15×3+11=56
There’s an increase in multiplier and addends. Let’s try:
- Next multiplier is 4 (adding 1), next addend sequence is 1, 1, 3, 11… (difference doubles, so next is 21). So, 56×4+21 = 224+21 = 245
- So, X = 245
Quantity II: 3, 2, 7, 16, 71, Y
- Pattern is a bit tricky, but looking closer:
- 3×1-1=2
- 2×2+3=7
- 7×2+2=16
- 16×4+7=71
Next, 71×4+16 = 284+16 = 300
- So, Y = 300
Quantity III: 14, 16, 28, 64, 144, Z
- This looks like:
- 14×1+2=16
- 16×1+12=28
- 28×2+8=64
- 64×2+16=144
Next: 144×2+32=288+32=320
- So, Z = 320
Comparing:
X = 245
Y = 300
Z = 320
Relations:
- X < Y
- Y < Z
So, X < Y < Z
Here’s what that means for your options:
- Option 1: X > Y > Z — nope, not it.
- Option 2: X < Y > Z — definitely not it, Y is not greater than Z.
- Option 3: X < Y < Z — yes, that fits.
- Option 4: X = Y > Z — not true, values are all different.
- Option 5: X = Y < Z — also not it.
So, you picked Option 2. Based on this,
The correct answer is Option 3: X < Y < Z
Option 3 is the one that matches.
Let me know if you want to check the patterns for any of these sequences in more detail!
