## The 5th Term Is 18 And The 9th Term Is 30. What Is The 16th Term Of The Sequence? A. 47 B. 49 C. 51 D. 53

Jawaban: #1:

Jawaban:

c. 51

Penjelasan dengan langkah-langkah:

The n-th term of the sequence formula

Un = a + (n-1) b

Un = the n-th term of the sequence

a = the first term

b = the difference between terms (beda/selisih)

U5 = 18

a + 4b = 18 …(1)

U9 = 30

a + 8b = 30 …(2)

Eliminate (1) and (2)

a + 4b = 18

a + 8b = 30

_________ –

-4b = -12

b = 3

Substitute b = 3 to (1)

a + 4b = 18

a + 4(3) = 18

a + 12 = 18

a = 18 – 12

a = 6

Un = 6 + (n-1) 3

U16 = 6 + (16-1) 3

= 6 + (15)3

= 6 + 45

= 51

Hope this helps.
