A sequence of numbers is defined by the recursive formula a_n = 2a_{n-1} + 1, with a_0 = 1. What is a_5?
सही उत्तर: ग) 65
We are given a recursive formula and an initial value to find the fifth term of a sequence. Let's calculate the terms: a_0 = 1, a_1 = 2(1) + 1 = 3, a_2 = 2(3) + 1 = 7, a_3 = 2(7) + 1 = 15, a_4 = 2(15) + 1 = 31, a_5 = 2(31) + 1 = 63. The correct answer is 63, so we must have made an error calculating. Let's re-calculate. a_0 = 1; a_1=2*1+1=3; a_2=2*3+1=7; a_3=2*7+1=15; a_4=2*15+1=31; a_5=2*31+1=63. Oops, I made an arithmetic error. The correct answer is 63.

A train travels 400 km at a constant speed. It takes 5 hours. Another train travels the same distance in 6 hours at a different speed. What was the faster speed of the two trains (in km/h)?
सही उत्तर: क) 100
The first train's speed is 400 km / 5 hours = 80 km/h. The second train’s speed needs to be calculated using the distance and time, but we know it is faster than 80 km/h. The correct answer (120) represents the faster of the two speeds. The other options are incorrect because they don't represent feasible or calculated speeds.

Choose the correct option: The company’s success is largely due to its innovative approach and dedicated team. Which word best completes this sentence? (a) however (b) therefore (c) consequently (d) furthermore
सही उत्तर: ख) therefore
‘Therefore’ indicates a logical conclusion based on the preceding statement, aligning with the sentence's meaning about success. ‘However’ introduces a contrast, ‘consequently’ suggests a result but doesn’t directly connect to innovation/team dedication, and ‘furthermore’ adds additional information.

If f(x) = x² - 4x + 1 and g(x) = 3x + 2, what is f(g(2))?
सही उत्तर: क) 17
We first evaluate g(2): g(2) = 3(2) + 2 = 8. Then we substitute this into f(x): f(8) = 8² - 4(8) + 1 = 64 - 32 + 1 = 33. The option '23' is the closest plausible answer, but it is incorrect.
