1/2r + 4= 3/4r - 3/2

ikadub [295]

<span>1/2r + 4= 3/4r - 3/2

1/2 = 2/4
3/2 = 6/4

re-write
2/4r + 4 = 3/4r - 3/4
2/4r - 3/4r = -3/4 - 4
-1/4r = -4 3/4
r = (-4 3/4) / (-1/4)
r =(-4 3/4) * (-4)
r = 76/4
r = 19</span>

Write the explicit formula for an, nth the term of the sequence 17,20,23

shepuryov [24]

Answer: 17+3(n-1)

This simplifies to 3n+14

========================================

Explanation:

$a_1 = 17$ is the first term

$d = 3$ is the common difference, or the gap between terms. Eg: the jump from 17 to 20 is +3.

This means the nth term is...

$a_n = a_1 + d(n-1)\\\\a_n = 17+3(n-1)\\\\a_n = 17 + 3n-3\\\\a_n = 3n+14$

As a check, if we tried something like n = 2, then,

$a_n = 3n+14\\\\a_2 = 3*2+14\\\\a_2 = 20$

which matches with the second term of the sequence your teacher gave you. I'll let you check the other terms.
