(5) 64 (6) 85 (7) 92 (8) 87 4 times 2 times 4 times 5 times

(8) 87 <br /><br />The pattern is to multiply the numbers in the left column by the numbers in the right column. <br /> <br /> 4 x 5 = 20<br /> 2 x 4 = 8<br /> 4 x 2 = 8<br /> 5 x 17 = 85<br /> <br /> Adding the results of each multiplication gives us 20 + 8 + 8 + 85 = 121. <br /> <br /> The final step is to subtract 34 from 121, which gives us 87. <br />
