    I didn't want to put my answer down just in case someone read comments before trying to figure it out.
    I figured it out instantly
    2 (x3) =6
    3 (4) =12
    4 5 20
    and on and on

  6. I used addition. The answers increase by two each time and add up. 6+6, +8, +10, +12, +14, +16, +18=97.

    So. which is "Right"?

  8. 2=6 +6
    3=12 +8
    4=20 +10
    5=30 +12
    6=42 +14
    (7=56) +16
    (8=70) +18
    9= 88
