(1.3) Sequence A: 4; 7; 10; 13; 16; Sequence B: 5; 10; 20; 40; 80; .......... Sequence C: 2; 5; 10; 17; 26; (1.3.1) Write down t
daser333 [38]

Answer with Step-by -step explanation:

Sequence A;4,7,10,13,16

a_2-a_1=7-4=3

a_3-a_2=10-7=3

The difference between two consecutive terms is equal. Therefore, it forms arithmetic sequence.

Common difference, d=3

a=4

a_n=a+(n-1)d

a_6=a+5d=4+5\times 3=19

a_7=a+6d=4+6(3)=22

a_8=a+7d=4+7(3)=25

Sequence B: 5,10,20,40,80,...

a_1=5,a_2=10,a_3=20

\frac{a_2}{a_1}=\frac{10}{2}=2

\frac{a_3}{a_2}=\frac{20}{10}=2

The ratio  of two consecutive terms is equal. Therefore, it forms geometric sequence.

Common ratio, r=2

a=5

a_n=a r^{n-1}

a_6=ar^5=5(2)^5=160

a_7=ar^6=5(2^6)=320

a_8=ar^7=5(2^7)=640

Sequence C:2,5,10,17,26,..

a1=2

a_2=5=2+3=a_1+3

a_3=10=5+5=a_2+5

a_4=17=10+7=a_3+7

a_5=26=17+9=a_4+9

From the following pattern

We can get

a_6=a_5+11=26+11=37

a_7=a_6+13=37+13=50

a_8=a_7+15=50+15=65
