18, 23, 10, 39, 22, 17, 16, 15 Mean = (18 + 23 + 10 + 39 + 22 + 17 + 16 + 15)/8 = 20 Lowest Number in set is 10 Highest Number in set is 39 Range = (39 - 10) = 29

If you're asking what the nineth erm is, it's 58. The pattern is to add 7 to a umber to get the next number. 2+7=9, 9+7=16, 16+7=23, and so on.
Every next number is increased by 5. The next number in the sequence is 23.
Each number is the sum of the two numbers before it: 4+5=9, 9+5=14, 14+9=23, 23+14=37... The next number is 37+23=60
The pattern is +5, +6, +7, so the next number will be 23 + 8 or 31.
The next number is 30+7 = 37.
18, 23, 10, 39, 22, 17, 16, 15 Mean = (18 + 23 + 10 + 39 + 22 + 17 + 16 + 15)/8 = 20 Lowest Number in set is 10 Highest Number in set is 39 Range = (39 - 10) = 29
5 (+5=) 10 (+6=) 16 (+7=) 23 (+8=) 31 (+9=) 40 (+10=) 50 The incorrect number is 42. It should be 40.
If the question is, What is the missing number in the sequence 7, 11, 23, ?, 167? Then each number is 3 times the previous number then deduct 10. 3 x 7 = 21 - 10 = 11 3 x 11= 33 - 10 = 23 3 x 23 = 69 - 10 = 59......the missing number 3 x 59 = 177 - 10 = 167 3 x 167 = 501 - 10 = 491....the next number in the sequence.
8/5 + 7/10 = 16/10 + 7/10 = 23/10 = 23/10
If you want to ask what is the next number of 23, then the answer is 24. If you want to know the next prime number of 23, the answer is 29.

The number 23 is 10111 in binary. The digits in a binary number are exponents of 2 rather than 10, so that for a five digit number in binary, the digit places represent 16, 8, 4, 2, 1 instead of increasing values of 10. 10111 = 16+0+4+2+1 = 23
The next number is... 30 because, each number is seven mire than the number to its left.
23/10 = 23/10.
23/10 = 23/10
