Take different values for x and find the value of 3x+5.​

X=2

3x2+5=

6+5=11

X=0

3x0+5=

0+5=5

X=1

3x1+5=

3+5=8

if x=1

3x+5.=3×1+5=8

when x=0

3x+5.=3×0+5=5

when x=1/3

3x+5.=3/3+5=6

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

i'm pretty sure the answer is a. decreases with increase in
