Explanation

Abu Marwan Ḥayyanwas an Arab Muslim historian from Al-Andalus. 

Born: 987 Cordoba, Al-Andalus (now Spain)

Died: 1075 (aged 87–88)

Explanation

This looks like an arithmetic sequence problem.
If the first term $a = 3$ and last term $l = 18$, and there are 4 numbers in between, the total terms $n=6$ (3 + 4 + 18).

The terms:
$a_1 = 3$
$a_6 = 18$
Number of terms $n = 6$

Common difference $d = frac{18 - 3}{6 - 1} = frac{15}{5} = 3$

The 3rd middle number is the 4th term:
$a_4=a_1+3d=3+3\times 3=12$

Explanation

The protests aimed to preserve the independence of the Supreme Court and opposed Netanyahu's judicial reforms, which were seen as weakening judicial checks and balances.

The current protests also demand Netanyahu’s resignation, holding him responsible for ongoing political crises, including the October 7, 2023 Hamas-led attack and the Gaza war.

Explanation

Equating the two expressions and simplifying gives:

$$x cdot 200 = y cdot 250 Rightarrow frac{y}{x} = frac{200}{250} = frac{4}{5} Rightarrow y : x = 4 : 5$$

⇒y​/x=200/250

=4​/5

⇒y:x=4:5

Explanation

We are given an arithmetic progression (AP):

10, 7, 4, ...

Step 1: Identify the first term and common difference

First term a = 10

Common difference d = 7 - 10 = -3

Step 2: Use the formula for the nth term of an AP:

Tₙ = a + (n - 1) × d

Find the 30th term (T₃₀):

T₃₀ = 10 + (30 - 1) × (-3)

T₃₀ = 10 + 29 × (-3)

T₃₀ = 10 - 87 = -77

Explanation
