The sum of 333 consecutive even numbers is 787878.
what is the second number in this sequence?

26

Step-by-step explanation:

First consecutive even number = x

 Second consecutive even number =  x + 2

  Third consecutive even number =  x + 4

Add:

 x + (x + 2) + (x + 4) = 78

 3x + 6 =78

 3x = 72

 x = 24

 The second number would be 26

 The middle number of a sequence of consecutive numbers can be found by dividing the sum by the number of terms. 78 ÷ 3 = 26

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
