The sum of first 5 consecutive odd numbers is:
16
18
36
25
We know that the sum of first n odd natural numbers is n2. Thus, sum of first 5 consecutive odd numbers = 52 = 25.
Twice the sum of 5 consecutive odd numbers and thrice the sum of 4 consecutive even numbers is 178. Thrice the sum of 5 consecutive odd numbers and twice the sum of 4 consecutive even numbers is 177. The difference between the sum of 5 consecutive odd numbers and 4 consecutive even numbers is
If twice the sum of 5 consecutive odd numbers and thrice the sum of 4 consecutive even numbers is 178 and thrice the sum of 5 consecutive odd numbers and twice the sum of 4 consecutive even numbers is 177, then the difference between the sum of 5 consecutive odd numbers and 4 consecutive even numbers is
