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:

  1. x
  2. x+1
  3. x+2
  4. x+3.

According to the question,

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

<h2>b)</h2>

(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
