Question

The sum of 3 consecutive even numbers is 270. What is the first number in this sequence?

Answer 1

Answer:

The first number in the sequence is 88.

Step-by-step explanation:

Given : The sum of 3 consecutive even numbers is 270.

To find : What is the first number in this sequence?

Solution :

Let the three consecutive even numbers be  x,x+2,x+4

According to question,

The sum of 3 consecutive even numbers is 270,

$x+x+2+x+4=270$

$3x+6=270$

$3x=270-6$

$3x=264$

$x=\frac{264}{3}$

$x=88$

So, First number is x=88

Second number is x+2=88+2=90

Third number is x+4=88+4=92

Therefore, The sequence form is 88,90,92.

Hence, The first number in the sequence is 88.

Answer 2

88 is the first. 90 and 92 are second and third
