Question 1043859

The sum of 3 consecutive numbers is 14 less than 1/4 of 176. find the middle number.
<pre>Let middle number be M
Then 1st = M - 1, and 3rd = M + 1
We then get: {{{M + M - 1 + M + 1 = (1/4) * 176 - 14}}}
3M = 44 - 14
3m = 30
M, or {{{highlight_green(matrix(1,6, Middle, "number", "=", 30/3, or, 10))}}}
