NEED HELP ASAP WILL GIVE BRAINLIEST REAL ANSWERS ONLY PLZ WILL REPORT FAKE ANSWERS

Contact [7]

Answer:

Step-by-step explanation:

There is a common ratio between consecutive terms

r = 24 ÷ 16 = 36 ÷ 24 = 54 ÷ 36 = 1.5 = $\frac{3}{2}$

This indicates the sequence is geometric with nth term ( explicit formula )

f(n) = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 16 and r = $\frac{3}{2}$ , then

f(n) = 16 $(\frac{3}{2}) ^{n-1}$ → C

What is the lcm of 16, 24 and 40

ivann1987 [24]

The answer is 240

Explanation: The Least Common Multiple (LCM) is the smallest number that two or more numbers will divide into evenly. NOTE: to find LCM you first need to know how to find GCD.

First we will find LCM for first two numbers ( 16 and24 ).

Step 1: Find the GCD (Greatest Common Divisor ) of 16 and 24 which is 8.

Step 2: Multiply the numbers 16 and 24 together ( 16 * 24 = 384 )

Step 3: Divide the 384 with 8. (384/8 = 48)

So, the LCM of 16 and 24 is 48.

Now we will find the LCM of above result (48) and third number ( 40 ) using the same procedure.

The result of this part is 240

What is the nth term rule of the linear sequence below?

hoa [83]

Answer:

$a_n=-5-2(n-1)$

Step-by-step explanation:

Since this sequence starts with -5 and decreases by 2 with each term, its rule would be:

$a_n=-5-2(n-1)$

Hope this helps!
