If you're looking for the value of the number, then here's how:
Let's call the number x
4x + 7x = 44
11x = 44
÷ 11
x = 4
So the number you're looking for is 4, if you wanted to know something else then let me know!

Write the recursive formula then determine the next term of 3,10,24,52
Schach [20]

Answer:

  • f[1] = 3
  • f[n] = 2·f[n-1] +4
  • 108

Step-by-step explanation:

We observe that first differences of the given numbers are ...

  10 -3 = 7

  24 -10 = 14

  52 -24 = 28

That is, each difference is 2× the previous one. This suggests an exponential relation that has a base of 2.

We notice that doubling a term doesn't give the next term, but gives a value that is 4 less than the next term. So, we can get the next term by doubling the previous one and adding 4.

Then our recursive relation is ...

  f[1] = 3 . . . . the first term

  f[n] = 2×f[n-1] +4 . . . . double the previous term and add 4

The next term is 2·52 +4 = 108.

Plaese help !!!<br> 5/7m=15
Darina [25.2K]

\dfrac{5}{7}m = 15

Multiply both sides by 7/5.

\dfrac{7}{5} \times \dfrac{5}{7}m = \dfrac{7}{5} \times 15

\dfrac{35}{35} m = \dfrac{7 \times 15}{5}

\dfrac{35}{35} m = \dfrac{7 \times 3 \times 5}{5}

m = \dfrac{7 \times 3}{1}

m = 21
