Answer:

2 3/4 or 2.75

Step-by-step explanation:

Cross multiply

1 ×

16 44

44 × 1 = 44

44÷ 16 = 2 12/16

Simplify 12/16

12÷4= 3

16÷4= 4

2 3/4

For each of the following sequences, • Give a formula for the nth term in the sequence, • Give a recursive definition for the se

Andrew [12]

Answer:

(a) $n^{th} = n$

$f(1) = 1$

$f(n) = f(n-1) + 1$

(b) $n^{th} = 2^{n-1}$

$f(1) = 1$

$f(n) = f(n-1) * 2$

(c) $n^{th} = n!$

$f(1) = 1$

$f(n) = f(n-1) * n$

Step-by-step explanation:

(a) This is a sequence of consecutive number

$n^{th} = n$

$f(1) = 1$

$f(n) = f(n-1) + 1$

(b) This is a sequence of 2 to the power of n - 1. The next number is twice time of this number

$n^{th} = 2^{n-1}$

$f(1) = 1$

$f(n) = f(n-1) * 2$

(c) This is factorial sequence. Where the next number is this number multiplied by $n^{th}$

$n^{th} = n!$

$f(1) = 1$

$f(n) = f(n-1) * n$

Find the solution for this equation<br> 2(h-8)-h=h+19

icang [17]

2(h - 8) - h = h + 19
2h - 16 - h = h + 19
h - 16 = h + 19
h - h = 19 + 16
0 = 35

Therefore, it has no solution.
