There is 20+40.
The sum of the first 10 multiples of 3 is 165.
If half of the sum is 90 then the full sum must be 180. The three consecutive multiples of 10 which add up to 180 are 50, 60 and 70.

5 + 10+15+20=50 ans
Two, whose digital sum is 5.
Two consecutive integers whose sum is 19 is 10 & 9; 10+9 = 19.
Write three numbers whose sum is 10 in all horizontal vertical and diagonal?
2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).
