c. is 78 a term of the sequence?
final answer
(answer with yes or no)
d. in which term/position will 632 appear in the sequence?
final answer: ……… term

Look at the following sequence

Jawaban:

a. 37, 44

b. Tn= 9+7n

c. no

d. 91

Penjelasan:

a. b= U2-U1= 9-2 = 7

maka angka selanjutnya adalah 30+7=37 dan 30+7.2=44

b. Tn=Un= a+b(n-1)

a= 2; b=7

maka Tn = 2+7(n-1) = 9+7n

c. (78-2)/7 akan menghasilkan sisa sehingga tidak termasuk

d. n= 1+[(632-2)/7] = 1+90 = 91
