Notice the picture below

thus, we know the total area is 70 square meters
now, if we add those areas, it should give us 70
thus

(5x)+(40)+(5x)=70 solve for "x"

The general term of an arithmetic sequence is tn = 32 + 3n, where n ∈N and n ≥ 1. The sequence is

Debora [2.8K]

Answer:

D) 35, 38, 41, 44, 47, 50,...

Step-by-step explanation:

The general term of an arithmetic sequence is

$t_n=32+3n$ , where n ∈N and n ≥ 1.

When n=1,

$t_1=32+3(1)=35$

When n=2,

$t_2=32+3(2)=38$

When n=3,

$t_3=32+3(3)=41$

When n=4,

$t_4=32+3(4)=44$

When n=5,

$t_5=32+3(5)=47$

When n=6,

$t_6=32+3(6)=50$

Hence the sequence is 35, 38, 41, 44, 47, 50,...

The correct answer is D
