Answer» Answer: Answer: The sum of smallest odd number and second largest even number is 163. Step-by-step explanation: It is given that the sum of 8 consecutive odd numbers is 656. Let the 8 consecutive odd numbers are x, x+2, x+4, x+6, x+8,x+10, x+12, x+14. x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)+(x+12)+(x+14)=656x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)+(x+12)+(x+14)=656 8x+56=6568x+56=656 8x=6008x=600 x=75x=75 The value of x is 75. The sum of smallest odd number is 75. It is given that the average of 4 consecutive even number is 87. Let the 4 consecutive even number are y, y+2, y+4, y+6. \frac{y+(y+2)+(y+4)+(y+6)}{4}=87 4 y+(y+2)+(y+4)+(y+6)
=87 4Y+12=3484y+12=348 4y=3364y=336 y=84y=84 The value of y is 84. The second largest even number is y+4=84+4=88y+4=84+4=88 The sum of smallest odd number and second largest even number is 75+88=16375+88=163 Therefore the sum of smallest odd number and second largest even number is 163.
