Write four more rational numbers of the following patterns:
2-3,-23,4-6,-69......
Given,
We have,
2-3=2×1-3×1,-23=2×(-1)-3×(-1),4-6=2×2-3×2,-69=2×(-3)-3×(-3)
Thus the following pattern is observed as
2×1-3×1,2×(-1)-3×(-1),2×2-3×2,2×(-3)-3×(-3)
Therefore following the same pattern next four rational numbers will be
2×4-3×4,2×(-5)-3×(-5),2×6-3×6,2×(-7)-3×(-7)
or,8-12,-1015,12-18,-1421
Hence, the required four rational numbers are
8-12,-1015,12-18and-1421
