Answer (1)
Answer:1. 62. 163. 10 4. 4.475. 125,625Step-by-step explanation:1-4 is solved using geometric means.m²=a sub 1 multiplied by a sub 21.) 3(12) = 36= square root of 36 is 6(common r is 2)2.) 4(64)256= square root of 256 is 16(common r is 4)3. -2(-50)100= square root of 100 is 10(common r is negative 5)4. 2(10)=20 = square root of 20 is 4.47(rounded off)(common r is 2.24, rounded off)5. It's solved by finding the common ratio and multiplying the common ratio by a sub 3 to get a sub 4 and a sub 4 to get a sub 5r = a sub 2 ÷ a sub 1r = 5÷1r = 5a sub 3 = 25a sub 4 = 25 × 5 = 125a sub 5 = 125 × 25 = 625
