Question

Four consecutive multiples of 3 have a sum of 78? What is the second largest number?

Answer 1

26

Explanation:

Let x be the first number

• the second one is x+1
• the third one is x+2
• the sum is : x+ (x+1)+(x+2)= 78
• so : 3x+3 = 78
• then : 3x = 75
• finally x = 25
• the second larger number is x+1 = 25+1 = 26
