The general pattern that these diamonds follow is that the top number is the result of multiplying the numbers in the middle; while the bottom number results from adding these numbers. This pattern can be used to find the numbers in the fourth diamond. Moreover, the numbers that complete the diamonds are A (15,8), B (2,-3), C (4,2), D(4,8.5), E (-3.-4)
<h3>What is the general pattern in the diamonds?</h3>
Based on observation, you can determine in these diamonds the top number is obtained by multiplying the numbers in the middle, while the bottom number is obtained by adding these numbers.
<h3>What numbers complete the diamonds?</h3>
Diamond A
Top number: 15 (3x5)
Bottom number: 8 (3+5)
Diamond B
Top number: 2 (-2x-1)
Bottom number: -3(-2+-1)
Diamond C
4, 2 because 4x2 = 8 and 4+2 = 6
Diamond D
Top number: 4( 8x0.5)
Bottom number: 8.5(8+0.5)
Diamond E
-3,-4 because -3x-4= 12, and -3+-4= -7
