You set 100 pixel jump in x-axis and 0 in y-axis. Try below code

    id jump_Up = [CCJumpBy actionWithDuration:1.0f position:ccp(0, 200)
                                    height:50 jumps:1];
    id jump_Down = [CCJumpBy actionWithDuration:0.7f position:ccp(0,-200)
                                    height:50 jumps:1];

    id seq = [CCSequence actions:jump_Up,jump_Down, nil];

    [sprite runAction:seq];
