    6 (+5)→ 11 (+10)→ 21 (+15)→ 36 (+20)→ 56 (+25) → 81, what about 25 , how do you get it?

    alternate solution by Ing. Justice Brown gh
    6, 11, 21, 36, 56, ?
    11 - 6 =5
    21 - 11 =10
    36 - 21 =15
    56 - 36 = 20
    this means that at next level 5 is added to the difference
    so the next number will be 56 + 25 = 81
