• A. 55
• B. 202
• C. 36.5
• D. 57.625
• E. None of these

Answer 1

Answer: (D)

57.625

Answer 2

From the series we can say that202

= $202 × \frac{1}{2} + 1^1$ = 102

= $102 × \frac{1}{2} + 2^2$ = 55

= $55 × \frac{1}{2} + 3^3$ = 36.5

= $36.5 × \frac{1}{2} + 4^4$ = 34.25

= $34.25 × \frac{1}{2} + 5^5$ = 42.125

= $42.125 × \frac{1}{2} + 6^6$ = 57.0625

The Error term will be 57.625

The Correct Term which will come in that place will be 57.0625

The correct option is (D): 57.625
