11) The sum of four consecutive integers is 290.

n200080 [17]

Answer:

71, 72, 73, 74 . for details, check below

Step-by-step explanation:

a) Let's assume that among the four consecutive numbers, the first one is x,

so, the four consecutive numbers should be:

x
x+1
x+2
x+3.

According to the question,

(x) + (x + 1) + (x + 2) + (x + 3) = 290

(x) + (x + 1) + (x + 2) + (x + 3) = 290

4x + 6 = 290

4x = 284

x = 284÷ 4

x = 71.

So, the numbers are,

71, 72, 73, 74
