S = (10 x1 /2) + (1/2x- 2x 1/2²)
5 + (-0.25)
= 4.75
Answer:
this rule follow the airthmatics progression.
Answer:
Table A
Step-by-step explanation:
looking at the two tables, we have the observations as follows;
For table B, if we divide x by y; we have a ratio of 2/3
This happens throughout the table
What this means is that x = 2/3 * y
But for table A, we notice a pattern for the first two lines
The pattern here is that x = 2y
But as we move to the next two rows, we notice this fails and thus, we fail to establish a pattern that works for all the rows;
Hence table B has a pattern for all its rows
60/7 = (56 + 4)/7 = 56/7 + 4/7 = 8 4/7
Answer:
7/9 = 42/n.
7n = 378,
n = 54.
