Question

The sum of 8 consecutive odd numbers is 656. Also average of four consecutive even numbers is 87. What is the sum of the smallest odd number and second largest even number

Answer 1

Answer:

161

Step-by-step explanation:

sum of 8 consecutive numbers = 656

x + x+2 + x+4 x+6 x+8 x+10 + x+12 x+14 = 656

x= 75

average of 4 consecutive even numbers = 87

(y + y+2 + y+4 + y+6)/4 =  87

y=84

y+2=86

sum of smallest odd number and second largest even number = 75 + 86 =161

Answer 2

Answer:

163

Step-by-step explanation:

avg of 8 consecutive no =656÷8=82

therefore 4th no is =82-1=81

therefore 1st no is =75

avg of 4 even no =87

there fore second even no is =87-1=86

second largest even no is =88

therefore required some=75+88=163
