Explanation

Current total marks = Average * Number of tests

= 60 * 4

= 240

New average = 65

New total tests = 5

New total marks = New average * New total tests

= 65 * 5

= 325

Marks needed in the fifth test = New total marks - Current total marks

= 325 - 240

= 85

Explanation

Now, let's examine the differences between consecutive terms:

17 − 6 = 11

39 − 17 = 22

72 − 39 = 33

The pattern of differences: +11, +22, +33 → increasing by 11 each time.

Next difference should be: +44

So,

72 + 44 = 116

Explanation: Differences follow a pattern: +11, +22, +33, +44.

Explanation

We use "a little" with uncountable nouns like "French" (as a language).

It means "some" or "a small amount."

Explanation

We are given:

$$$$h3=64

To find the value of h, take the cube root of both sides:

$$$$h=3^√64 =4

So the value of h is 4.

But the question asks for the value of n, not h.

Since n is never defined, we cannot determine n from the given equation.

Answer: (D) None of these (assuming it's not a typo and the question asked for "n").

If the question meant "the value of h", then the answer would be (B) 4.

The Paschen series involves electron transitions ending at the third energy level (n=3) in a hydrogen atom.

These transitions emit photons in the infrared region of the electromagnetic spectrum.

Explanation

"If you lose your passport, you will be in great trouble."

In a first conditional sentence, we use the present simple tense in the if clause and the future simple (will + verb) in the main clause.

Here, "lose" (present simple) is correct because it is used in the if clause to indicate a possible future event.

Explanation

When using future perfect tense ("will have passed"), the clause with "when" takes present simple tense — not future.

So, the correct sentence is: "Three hours will have passed when the bell rings."
