5 (+6) 11 (+5) 16 (+5) 21 (+5) 26
Apart from (+6), there is an increase of 5, as shown in the brackets above.
composite numbers between 11 and 21:12 14 15 16 18
16 and -5
Your answer is 16 & 21 21 - 16 = 5 21 * 16 = 336
To create a set of five numbers that meets these criteria, we can use the numbers 21, 21, 15, 14, and 10. The mean is ( \frac{21 + 21 + 15 + 14 + 10}{5} = 16 ), the median is 15 (the middle number when arranged in order), the mode is 21 (the most frequently occurring number), and the range is ( 21 - 10 = 11). Thus, this set satisfies all the given conditions.
Let the two square numbers be ( a^2 ) and ( b^2 ), where ( a^2 - b^2 = 21 ). This can be factored as ( (a-b)(a+b) = 21 ). The pairs of factors of 21 are (1, 21) and (3, 7). Solving these gives the pairs ( (11, 10) ) or ( (5, 4) ), leading to the square numbers ( 121 ) and ( 100 ) or ( 25 ) and ( 16 ). Thus, the two square numbers can be ( 121 ) and ( 100 ) or ( 25 ) and ( 16 ).
11 and 31 and all the fives between numbers.
It is 16. This is because there are five numbers between 11 and 16, and there are five numbers between 16 and 21 :]
composite numbers between 11 and 21:12 14 15 16 18
16 and -5
Between 11 and 21: 12, 14, 15, 16, 18 and 20.
1, 6, 11, 16 and 21
To find the seventh term in the sequence -6, -11, -16, -21, -26, we first identify the pattern: each term decreases by 5. Therefore, the next term would be -26 - 5 = -31. Continuing this pattern, the seventh term would be -31 - 5 = -36.
n=5, n is the sample size.
58 - 16 = 42, 42/2 = 21, 21 + 16 = 37. Your numbers are 21 & 37
Your answer is 16 & 21 21 - 16 = 5 21 * 16 = 336
