the answer is 12
20 + 3 = 23 23 + 5 = 28 28 / 2 = 14 14 + 3 = 17 17 + 5 = 22 22 / 2 = 11 11 + 3 = 14 14 + 5 = 19 19 / 2 = 9.5
add and divide by 4 average is 49
5, 8, 11, 14, 17 = has a1 = 5, d = 3, and n = 5.The explicit formula is an = 5 + (n - 1)·3
3n - 1
The average is 12.
the answer is 12
x = 5
The average is 14.
Average = 13
Since 5, 17, and 14 have no common factors, simply multiply the numbers together: 5*17*14=1190
17 - (8 - 5) = 14
The GCF of 5, 14, and 17 is 1.
It is 16.66 recurring.
13.333 recurring.
20 + 3 = 23 23 + 5 = 28 28 / 2 = 14 14 + 3 = 17 17 + 5 = 22 22 / 2 = 11 11 + 3 = 14 14 + 5 = 19 19 / 2 = 9.5
the average age is 14-18 or 14-17. other age ranges include 15-17 15-18 15-19 15-20 and 14-20, but the average is 14-18
